I like Linkin Park, The Killers, Maroon Five, GREEN DAY and Coldplay. Sometimes. I only listen to Coldplay when I'm really tired and can't sleep :P Getting to the 21 century, I like Lady Gaga, Jason Derulo, Katy Perry, B.o.B and... Shane Dawson if he counts There are also some really good singers on youtube (such as Shane) who make funny songs and music videos. One more serious singer on youtube is Chester See. You should check out his videos
I love BFMV also. I only listed the bands I like/have liked the most. I might as well put other bands that I love to listen to, because it would be spamming and trolling if I wasn't: Led Zeppelin, In Flames, Pantera, Godsmack (I'm starting to like them a little bit, although I didn't at one time, then I went to Mayhem and they killed it), Hatebreed (representing Connecticut ), As I Lay Dying (they're pretty depressing but I can't deny that their music isn't good), Red Fang, Unearth, Iron Maiden, Meshuggah, Lamb of God, and Slayer. But aside from the metal, I also like Taylor Swift a lot, the Foo Fighters, Green Day, The Beatles, Jimi Hendrix, The Doors, Radiohead, Ted Nugent, yeah you get the point.
