I agree
but you can't generalize it, of course there's huge drop in quality, originality, creation and innovation in the music industry after 2000
this year is mostly Adele (well deserved, quality music)
in my opinion it got worse after 2006, where the pointless ''we are dancing in the club'' style songs got a terrible fashion, there are still some great songs, if you have the time to search online, but most mainstream songs are annoying ''dancing in the club songs'' which don't last more than 2 months anyway
2004 for example was an amazing year, Avril Lavigne, Evanescence, Green Day, Usher, also the winner of Eurovision 2004 (Ruslana - Wild Dances) was fresh (if anyone knows, a European music contest)
don't mind my username, that was more than 10 years ago, I'm a different person now, amazing how people change ^_^
