Doesn’t even have to be music, really. Some bands and artists are famous for being hated, like Nickelback.
But which ones do you like?
I like Coldplay, a band that Noel Fielding thinks is totally bland and forgettable. I’m a fan, though, especially their last three albums.
Kesha
I think I may have heard you mention this artist before? 
Coldplay are MOR Secretary Rock. 
I’ll say… Bon Jovi.
I would go back and listen to tracks off Ted Nugent’s first couple of albums if he wasn’t such a moronic douchebag. Stuff like Free for All, Just What the Doctor Ordered, Hey Baby. Haven’t listened to them in 15-20 years.
The Bee Gees. Most people know and hate them for disco (which I liked), but they did a lot of good music after that.
And before.
For me, there are some bands that I have a love/hate relationship with. Like U2, an old favorite from my youth, but I just can’t stand the fucking face of Bono and all the pretentiousness. But damn, All I Want Is You and* One* get me every time, and even the most pretentious of their albums,* The Joshua Tree* and Rattle And Hum still are great music. And Achtung Baby was a very clever move and good music, too. But sometimes I hate them. Just like Sting, though Police were my heroes in the late seventies, and I still like to listen to them from time to time, even went to one of their comeback gigs in 2008. But Sting, well, see Bono above, and most of his solo work is crap, though I like his early live album Bring On The Night.
And then there’s the case of the Eagles. I’m a big fan of country rock, but they single-handedly killed the genre by watering it down beyond recognition, they just had no edge at all. But oh the melodies, and the harmonies! I still can’t decide if New Kid In Town is a sappy piece of schlock or the sweetest song ever, but every time it plays on the radio, I’m singing along wholeheartedly, so I guess I like it ;). But I cheer every time for the Dude in The Big Lebowski when he says his famous line about the Eagles. I’m torn.
My friends seem really pissed at how much I like Sublime. Their loss!
I love the Eagles. “Edge” isn’t all there is to music. Not that I don’t like edgy stuff, but it isn’t always necessary. And something like Hotel California may not be edgy, I think it’s far from bland. I find it lyrically interesting. And any band that has Joe Walsh on guitar has to have a tiny bit of edge, right?
Insane Clown Posse
Kesha
Dirt Nasty
Riff Raff
Kreayshawn
Lil Debbie
Lil Dicky
Rebecca Black
And although I don’t know much of their other music, I am proud to have Aqua’s “Barbie Girl” on my phone.
The Shaggs, believe it or not. (That they’re hated, of course.)
Pretty well just about everything else I listen to.
the ramones sex pistols … and any 80s to mid 90s rap …I admit that a certain individual that had a beef with the la co sheriffs was known to blast a bootleg of ice-t/body count’s cop killer when they visited the block but we never figured out who …<whistles innocently >
1980s era Genesis. And Phil Collins’s solo stuff too.
Threads like this are funny. They make me reflect on what a musical hypocrite I was when I was young and stupid.*. Even while, as stated above, I was a committed anti-Disco, ant-Country, etc guy at a time when it felt like that stuff mattered, man!
I was the musical equivalent of a Junk Food Junkie, where I was Rock-ier Than Thou during the day, but loving songs like Donna Summer’s I Feel Love and Gloria Gaynor’s I Will Survive (yeah, overplayed, but a surprisingly well-crafted song. Cake’s version opened a new door for me, too).
I have yet to figure out who is hated and who is loved. Folks I think of as “physical laws” of foundational musical joy leave other folks cold. So it goes. Some legends leave me cold.
I mean, look at Punk. Punk is such a pose is so many ways - the music was stripped down roots rock n roll at its essence. Folks hated the confrontational style of punks and Punk’s pose, but when time passed and its trappings and musical style got woven into the mainstream, the music has become part of our beloved sonic wallpaper.
*now I’m an old fool, which is better 
For some reason, American sitcom writers consider the words “Billy Joel” to be an automatically hilarious punchline. I have no idea why. Sure, he’s a big ol’ dork, but his music is great.
Every “hated” act is enormously popular. Remember that.
If “everybody” hated Nickelback or Creed or Justin Bieber, how’d they sell so many recordings? How’d they fill so many arenas?
I was a huge fan of all the pompous pretentious prog rock bands of the 70s. CRITICS sure hated Yes and ELP, but they had loads of gold albums and lived in mansions. Obviously “everybody” didn’t hate them.
I was watching “I Want My 80s” last night, and a Genesis video came on. It made me mull about how unlikely a megagroup Genesis was in the video era. Phil Collins looked like a bank manager who needed a haircut.
Maybe twice or thrice.
If Billy Joel is “hated,” that counts for me – sure, he’s a Broadway musical composer trying to rock out, but his late 70s music is great.
I’m sure Ricky Martin gets little respect among the musical cognoscenti, but he had two albums in the 1995-97 period that were quite good and wide-ranging (and he contributed to composing some of the songs).
Are the Grateful Dead frowned upon? They built a sort of unique-yet-timeless Great American Songbook between '69 and '74.
