Serious Music Player help

I’ve been messing with this for almost six hours now and am at the end of my wits. I need a flash mp3 player that follows the following guidelines:

*all encased within its own movie clip
*loads four different songs, one after the other (event)
*each song displays its own loader
*user scrolls through song selection and plays available (loaded) ones
*first song plays when loaded and continues to the others

any tips on where to go with this? do I create four different sound objects since later songs are loading while the first are playing?
