Doesn’t work like that here. Incidental use (ie., personal listening) is okay, even at businesses. If you’re playing the radio to entertain customers it’s a bit different.
Why can’t you just get an iPod and some speakers and blast Aphex Twin all day? They’ll sue for peace in under a week.
“Damn, Hot 105.5 is off the air AGAIN today!” 
I have just found this thread from 5 years ago, and I know it is VERY late to respond but I just have to put forward my story on this subject.
I was put in a similar situation at my workplace, only this was far worse. I was asked to chip in for a new radio with my work colleagues every time it broke. The last radio we bought was a DAB, which I chipped in £20 for. The radio did not work anywhere else in the room apart from where I was working near the window on a guillotine every day, and my supervisor decided to stick one of the speakers slap bang in my face. After a while, I found a radio station which I really liked and everyone agreed on it, until a few months down the line. I had a week off work, came back, and the radio was on a different station which played the same old commercial shit every day which I could not stand. I was told that everyone else wanted it on that station so I was outnumbered. When my supervisor wasn’t there I started tuning in other stations and saving them on the presets. Other people I worked with wanted all those different stations but it was still right in my face every day and not even near any of them!
I came up with an idea to make a radio rota so all our desired stations would all get a fair play throughout the week. People thought it was sad that I did this, but it was right in my face and I had every right to hear my desired station too. This worked for a few weeks, until my supervisor pretty much banned me from having the station I like coz he said it was shit, and that I’m not to touch the radio again. Therefore I just had to listen to their stations everyday right in my face with not so much as a single say in the matter. He didn’t like their choices in radio stations either, but he only ever had the guts to have a go at me about mine.
Eventually, I asked for it to be moved away from me, or else I would be taking the matter further and having a word with the general manager. I was told everyone will hate me if I do that, which annoyed me even more. My supervisor then decided to move the radio, and because it wasn’t near the window where I worked on my guillotine, guess what - the reception kept cutting out! They all blamed me and said it was all my fault coz I asked for the radio to be moved. I said that it was a total pisstake and that they wouldn’t like it if they had to work with a speaker right in their face everyday with other people’s choice in music - especially when you’ve chipped in £20 for the bloody thing too so I wanted my money back.
A few weeks later, the whole workplace was moved around and the radio was put the other side of the room well away from me. We are now in a brand new building where the radio is nowhere near me and stuck playing a ‘‘same old shit’’ station every day. I hate same old boring commercial music, but unfortunately it’s what most people want and they force it on others which is simply not fair. It’s as if you are forced to like it. There’s CCTV cameras up now everywhere spying on everyone working, so no way am I gonna get involved with the radio or bring in my own. The bosses will see me faffing about on their Big Brother CCTV cameras, so instead I leave the others to it to sod about with the radio and put on whatever they want - despite it only works on one station in this new place. They will be the ones who will be caught out, not me.
The honest advice I can give to anyone whose been in this situation is - When you are at work, act like you don’t like ANY music! I act like a right miserable bastard now where the radio is concerned. If they ask me what station I like I tell them I hate all radio stations and I hate all music. I say that I don’t want the radio anywhere near me, and if it is put anywhere near me I will smash it to bits. No say, no pay. Not interested in it, don’t care about it, don’t wanna hear it, don’t give a shit what’s on it - just as long as it’s far away from me, and if they hate me for that then GOOD - I don’t give a shit and I want them to hate me. Of course I don’t really hate all radio and music, it’s just an act. I now keep work and music completely separate. I want them to all think I’m a miserable old sod who likes nothing but work, it gives me great joy and pleasure.
One positive thing has come out of all this - the boss and general manager seem a lot happier with me these days. They’re not into any music themselves at work and have always been against the idea of anyone even having a radio. We are not allowed to wear headphones either. Remember again that this is all an act on my behalf - me acting miserable like I hate all radio stations and that I only care about work. Just work work work is all I care about when I’m there, as that is what gets the company up the ladder - not what bloody radio station people want on. When I get home, my music is whacked on without any complaints and I’m safe in the knowledge that my boss is happy with me. Act miserable at work by hating all radio stations and make sure nobody puts their radio anywhere near you, and if they do - bloody well smash the f**ker into a million pieces!!!..
This happened to one of the work places where one of my family members used to work. They used to allow the radio, but there were complaints about the radio station choice (usually Heart FM, or Radio 1, in the UK). Then a rota system was used, but there were more complaints. Result? Total ban of the radio, and the license to have the radio on got stopped. (In some workplaces you have to pay a license fee to have a radio on, or any licensed music.)
Thankfully, that person no longer works at that place!
Sounds a bit like Heart FM, which is my “local” station in the UK!
I’m not surprised that you don’t want to listen to it. I’d say get one of those little portable FM transmitters, as in the ones that send a signal from your iPod to your car, and tune it to whatever frequency the local radio station is on. Then use your own source of music, such as a mobile phone, iPod, internet radio etc. That will solve the problem.
I don’t really have an answer, not having worked for an office full of old people in 1987.
Seriously, radios in the office? People can’t listen to their iPhones or Spotify on their computer if they need their daily dose of Katy Perry & Ed Sheeren featuring DJ Khaled, The Chainsmokers and Coldplay (David Guetta remix).
Or, if you want to be mature about it. Play this at levels just barely audible. It is a musical tone scientifically proven to induce anxiety and agitation. Chris Nolen and other filmmakers use it to create a heightened sense of tension in their films. You can use it to induce madness in your workplace.
Have you seen Vi Hart’s video on Shepard Tones? It’s pretty cool.
I think it’s completely reasonable that if they’re going to put the radio right next to a person, that person has a say in what gets played on it. And I feel very sorry for all the people who are not allowed to stream music from internet radio.
I worked shelf stacking overnight at a supermarket for a while and they would put the same CDs on the tannoy all night long every night. Absolute maddening garbage. So I hid the CDs and substituted one I burned off with the same Britney song on it twenty times. They soon got the message and we took turns bringing in CDs from home after that.
That seems like a strategy that could have easily backfired. 
At work I sometimes have THREE different sources at the same time. That will drive you crazy.
This is a felony. Do not do it.
This post is from 2010, OP has probably burned the building down by now and is in prison.
OP hasn’t been online here since 2014. So, maybe.
What’s the typical sentence for arson?
Might not have been a solution in 2010, but nowadays you could use bluetooth headphones (so no tether to your desk) with a built in microphone (so it acts as a phone headset too). I just bought a pair for $15, so they aren’t pricey.
Only issue I foresee is if your work phone and cell phone are different, but you could probably forward your calls so that calls to your desk phone will ring and can be answered on your cell. As long as you have decent cellular service.
Since you’ve resurrected the thread, you should know that workplace radios may require a licence from the Performing Rights Society.
Ah, I see I made the same point some years ago!
Check Amazon for FM transmitters that are used as bluetooth or Aux adapters in vehicles. Just make sure to get one that can be programmed for the entire 88-108MHz FM frequency range.
Here’s an idea for revenge.
