Is there an audio hosting site that converts mp3s to URL so I can put my own songs (not videos) on M

I'm trying to take my own songs that I have downloaded onto my computer and put them on my Myspace profile. There's a site that allows you to do that (Myspace Support.com) but it's asking for the song's URL. Can I take my own audio files and convert them to URL, or do I have to go to a site and get the songs from there? And if so, where is the best place to find songs (not videos). I saw questions that were similiar to mine and the answers only led me to video sites. That's also all I seem to come across when doing a search for "Myspace songs". Any help would be greatly appreciated.
