I remember seeing a thread like this a while back on TWCC... Be prepared ...
-100% any rap/hip hop.... its garbage and may be a large contributor to the demise of America's youth. I consider it noise pollution
-any type of boohoo /antagonistic/break up song.. like the one who writes "im not gonna write u a love song" or some crap like that and the stupid cheating song by carrie underwood.. i mean get over it, ya know?
-any type of vulgar song
-any type of vocal song, period. I dont hate vocals (like the extent that I hate rap/hip hop), but I never been a big fan of lyrics anyways...I wouldnt buy an all vocal CD
and less than 5% if my music collection has vocals
-and any of the above already mentioned previously in this thread as well
