while mp3s are nice dont forget to look in to the licenceing for them if you ever plan to go commercial with your project. I suggest using the ogg format. Just my opinion. I looked into the mp3 licence and its pretty expensive. not worth it in my opinion. Anyways just wanted to point that out. However a little off topic. Im curious if we need a licence if we create an app that can play mp3s but dont include any mp3s themselves.
