60% of the music is bad...but right now i´m thinking:
most BSB songs (almost every boy band song, only n´sync did some decent ****!)
most britney songs(esp. do somethin´, not yet a girl...and oops!)
99% of the disney songs
70% of the 50 cent "songs"
most teenpop songs(i.e. jessica/ashlee simpson, britney, hilary, mandy etc. ...even xtinas first record and stripped has some bad moments, esp. the debut, but she weighs it up bigtime
)
90% paris hilton (stars are blind has a LITTLE charm)
etc, etc, etc....
the good thing is that this year i´ve felt like the "mainstreammusic" and big songs overall has one of it´s best years for a looong time, maybe thanks to internet!
