IMO several reasons contribute to this feeling
1) so many releases make it hard to find the good stuff
2) music in general has become a business and like books (remember them?) once a formula is found you just keep repeating it rather than explore new things and expand
3) producers have taken to compressing the hell out of the songs for mp3, etc.
There is still a lot of good "new" stuff - you just have to sift through a lot of crap to to find em.
