Back in high school I used to think that way too. Pretty easy to give up on today's music when you listen to any radio station and compare it to the gems from the past.
Dunno if I matured or what, but now I've definitely got an appreciation for all types of music, new or old. Good music is still being made, just gotta find it and listen to it with an open mind, and avoid the top 40 bullshit at all costs.
