Ubuntu Multimedia :: How To Build A Music Media Center

I am trying to build a media center for music for me and my roommates to use. Basically I want to build a system just for playing music. Idealy (dare i mention itunes in here) I would love a computer just just booted into itunes(orsomething like it (or better) that just was for playing music.

I plan on buying a computer, like a tiny desktop (i dont want to take up a lot of room) with a huge hard drive just for holding music, and needs usb drives/cd drive for loading music onto it (or just a usb drive). Then get a small screen, not huge with a remote that does not run on wife. Also would like a keyboard on the remote if possible.

Anywho whats a good media center, and can I boot just straight into the media center? I would like support for; browse by artist, album and just song name. Also I would like to be able to make playlist within it, and it needs to be able to support a massive amount of songs.

desktop computers to use for this project and remotes that I could use? Also how would you suggest the best way to go about doing this? I would love if it booted straight into the media player. Internet is not a huge deal to me, might connect to internet once just to grab album artwork. So a media player that auto fetches artwork too would also be nice.
