personally, i think the psp is not good if you are using it as a music player...

ive been using the psp slim for almost 2 months now.
the psp's music player application for me is bad especially in browsing songs.
it takes a long time to browse if youre going to listen a artist that starts with an alphabet that is way back at the end(X,Y,Z),the time it takes is sooo annoying(for me) especially if you have about 300 songs (like me)...

but i always look at the good part of my psp as i mostly use it for games and video watching as it is a multipurpose gadget...in the end nothing is perfect...
