I agree completely with ILJP and everyone saying this is a music forum and that variety is the spice of life. *hugs you guys*
The reason classic rock and modern pop are, without question, my two favorite genres of music... is because they both are packed with hooks, with universal lyrics, with stark, emotive singing. For every one 10 minute jam any of the biggest classic rock bands did, they did ten 4 minute pop songs.
After rock music stopped being new and exciting for me, I spent a lot of time in the underground looking for things to make music feel new again. And I found a lot of cool stuff: indie rock, and black metal, and noise and riot grrrl.... What I found, though, was that this stuff would be new and exciting, but it wouldn't stick with me. I wouldn't still be listening to it a year later, I wouldn't learn every song by heart, it wouldn't become a part of me, like classic rock did.
What they were missing were the hooks and the universal lyrics. I never noticed, but classic rock and pop are closely related. If you look at an album like Blood on The Tracks, Petty's Wildflowers, Harvest, anything The Beatles ever put out... there are a lot more connections to Taylor Swift than there are to Arcade Fire. And hey there's nothing wrong with indie rock! But it is what it is. Monster choruses, lush organic instrumentations, modest production, simple song structures, stark vocals, honest lyrics about life and love... That perfectly describes Taylor Swift, and Tom Petty, and The Beatles.
If you wanna go listen to straight up noise music that's cool with me, I recommend Boyd Rice (a.k.a. NON) and Wold. But to praise Bon Jovi and categorically despise Justin Bieber doesn't make sense, and it may even verge on hypocritical. I mean you can say Jovi writes their own tunes... but if songwriting credits meant all that much to you, you'd never listen to Aerosmith's I Don't Want to Miss A Thing, Bob Dylan's debut album, or 50% of Led Zeppelin's discography! I mean heck, Roger Daltrey didn't write very many of the songs he sung, is he not a good vocalist? I have a hard time believing people really care all that much about who wrote a song. A good song is a good song, period.
Nobody here has to dig on modern pop. But to attack it doesn't make much sense when you look at the stuff you listen to... These are almost all chart bands, it's not like this is a black metal message board. And I'm sure glad it's not, because rock and pop are my favorite genres.
