Up pops a little window with a media player, playing the song.

Basically, create an media GMail account. Mail yourself MP3s with any relevant information you want to be able to search on in the body of the e-mail. You can use labels for artists, genres and albums. And *bam* wherever you have net access, you have music/sound.
I wish I had more time to play with it now. But, I'm definitely going to once I'm back from vacation...
