I used to be extremelly narrow minded for music...it's funny how in only one year (2003) my music tastes changed so much i'm open to a long variety of genres now. It really depends on my mood for me to get to appreciate a certain genre. Like I LOVE listening to ballads when I'm physically and mentally exausted, it has such an interesting effect over my sleep. I usually like to stick to danceable songs because they usually have catchy melodies and well dancing=exercise which is a good thing, makes me get into a much better mood!
