you could use yousendit, but you'd have to upload song by song.
bumpman is right, mp3 quality is really poor, bittorrent and b&p is mainly for lossless audio.
you can also set an ftp server. i use quick 'n easy, that's the easiest ftp server i've tried. with the server you can make one or more folders accesible to any computer.
