I agree with Razor Leaf 500% here. Only two or three albums in my iTunes are entirely clean but I find that I personally enjoy the more 'explicit' albums more, because it's so much more uninhibited and common among the genres I enjoy.
Personally, I don't care how clean or how explicit a song is. If I like it, then I like it. I could listen to the most G-rated music and go to listen to Eminem the next minute, I seriously don't care.
Plus it's a whole other debate as far as 'good music' and 'bad music' goes.
