i used this same code and i am able to see the songs list but when i click on any item it is not playing.Please share the xml files as well.

This tutorial is worthless for begineers without the source especially the xml layout files :)

Not bad... but a tutorial containing just plain source code without explanations/comments isn't a tutorial, or at least isn't a good tutorial. Just my opinion.
Anyway, thanks, because it helped me a bit to clarify things.
