How do I use music from my computer (i tunes) on my xanga?

i dont think you can... although, i'm sure there are people out there who know how to do it.. but honestly, i think you havet o get the music from offline. But i'm sure there are sites with your songs on them...

if you use itunes music store, i dont think its possible because its encrypted in aac format... so that you don't mass produce, but it is possible sometimes, if you have another version of it or its not bought from itunes, you upload it to a decent webhost like angelfire.com and host it there
then use a link to the song as your music url
