I, personally, don’t listen to much Top 40 stuff, though some of it is definitely okay (and there’s been some earworms). However, there are tons of recent bands that are pretty cool. I like Streetlight Manifesto and Chase Long Beach for ska. KARA and BoA are pretty decent from the East Asia/Korean* pop scene. Of course, there’s always the older hats that still product music, Nightwish is from the '90s but they still do fairly good symphonic metal. MC Frontalot is “borderline” new (1999), but his nerdcore rap can be good – the very recent Epic Rap Battles of History Youtube channel also makes some catchy stuff. Jonathan Coulton makes good… uh… folk pop indie rock? Sure, let’s go with that. The Darkest of the Hillside Thickets (1992) are damn good… uh… Wikipedia says punk. Abney Park (1997) does good steampunk/industrial music. There’s also a few of the old bubble/dance/europop bands doing their thing to good success, like Smile.dk. There’s… uh… whatever the hell the Animal Collective does. Voltaire does some deliciously dark catchy music in a genre I can’t define (Wikipedia says “dark cabaret”).
You might like Cage the Elephant. I’ve heard people compare them to The Eagles (though I’d say they’re much closer to The Ramones). Their second album is a bit weirder though, not-quite-but-almost prog rock-ish to my ear. I’m not sure you’d like them, but I know a lot of Eagles/Fleetwood Mac people who take to them.
Now, I’m 23, so your question isn’t directed at me, my point is mostly that there are tons of artists that your students probably don’t listen to because they’re not popular (and the ones that do listen to it probably only talk about it with like-minded individuals, not with all the popular kids in class). Lots of bands are putting out good music in basically all genres (hell, that list was nowhere near an exhaustive list of the relatively new artists I listen to).
The pop isn’t bad, but pop never appeals to everyone. Is it mostly vapid and overproduced? Sure, but that’s pop for you. Maybe three or four trailblazers and then a bunch of copycat followers. And, as always, even the trailblazers put out 90% bland forgettable stuff, but that’s true of any band in any genre. And, hell, looking at the current Billboard “Hot 100” there’s a LOT of variance on there. Just from the ones I recognize in the top 20: P!nk, Bruno Mars, Justin Timberlake, Lil Wayne, and Fall Out Boy. Some of those are more similar than others, but I’d say there’s at least three distinct genres in that mass (it gets a lot fuzzier with subgenres).
Like I said, I can’t really vouch for/against the popular stuff too much. I’ll let someone else defend the Beyonces and Katy Perrys, but music is pretty good right now – if for the sheer number of bands consistently putting out albums more than anything else.
- I say “East Asian” because Korean bands (esp. girl bands) seem to have a tendency to make some singles in Japanese that get fairly popular. Granted BoA also did an English album IIRC.
