David Bowie? I could never stand him and I believe he's just an awful singer. Any guilty music pleasures? Hmm, I'd say that probably someone like Cat Stevens is too old for others but I like his music. A former guilty pleasure was that I liked Linkin Park, Nickelback and Eminem. That makes me embarassed just thinking about that.
If there is anyone on this site who listens to that Crazy Frog or whatever, I'm going to hunt you down, kick you in the stomach and force you to listen to every last 'song' that was made by it, OVER AND OVER so you know what it's like for the rest of the civilised people who have to put up with it on those ringtone ads. Seriously, if I ever listen to Crazy Frog on my own free will, someone shoot me.
