That it im moving to linux

^_^ Im planning to screw microsoft in the ass :)
Im moving to linux from windows (Im going to use ubuntu) but  I need to know some stuff

1. What's the best MP3 player for ubuntu?
2. What exactly is WINE? Does it enable you to run windows programs? (I need to get my mp3 player software working on linux)
3. Is there any essential applications which would be tremendously useful for editing pictures (like GIMP) or anything like that?

Worth pointing out that due to patent issues, mp3 doesn't work out of the box in Ubuntu. However it's dead easy to get working. Follow the instructions in this guide: https://wiki.ubuntu.com/RestrictedFormats
Takes maybe 10 minutes and you'll have all your codecs both free and non-free as well as Flash, Java and (if you're a fag) access to iTunes music store.
