Well if you were a beginner on Audiotool, I'd suggest talking to other people about creating music and such, asking for productive criticism, or trying to enter remix competitions. Talking to other people about creating music could get them wanting you to create and they will listen to it. Since you're a beginner, it won't be your best and there will be things to criticize, and they will do that until they feel you're at a point where you can create beautiful music, but they would have to listen in order to know what to criticize. Going to professionals and asking them if they can critique your tracks in their free time WITHOUT putting a single link on their wall could also work, so they can help you create better tracks. Entering remix competitions can allow the judges to listen to your music, but this is a 50/50 chance kind of thing. If they like your entry, they might want to go to your page to listen to more of your tracks, if they don't really enjoy their listening experience, then you might want to reconsider the other two choices. If none of those work, just do what I did. Wait until someone starts roaming around the wasteland of Audiotool accounts and stumbles upon your account and wants to listen to your song, after a while, you might be dragged out of that wasteland and start getting some attention, slowly, but surely.
Patience. It takes years of hard work
