I've pretty much boycotted every major music radio station in California.
I hate the radio (keep in mind, I'm talking about traditional radio here, not online radio). They usually don't play anything good, let alone anything you want. And I hear to this day radio stations are anal about doing anything that even comes close to playing a wide variety of bands...just the bands that'll net them the most money.
Here's a nice little tidbit I picked up a while ago: next time the station is playing some Top 40 drivel, emo, butt-rock (Linkin Park, Nickelback, Maroon 5, Coldplay, etc), gangsta rap, fake "metal" (Slipknot, Limp Bizkit, Avenged Sevenfold), pop nonsense, or anything else that's guaranteed to net in MTV watchers, take careful note of the time. Listen to that same station the next day and more often than not, you'll hear the exact same song within 20-30 minutes of the time you noted down the previous day.
I'll stick to using Spotify, putting in playlists I've made personally, or CD's I've bought that kick ass.
