I designed a simple jukebox-style flash sequence for a client of mine about a year ago. It plays MP3 files named 1.mp3, 2.mp3, etc (all the way up to 4). It doesn't display a trackname or an equalizer, but they can always be added with the use of external plugins or just a simple textbox. You can find it attached to the .zip below. I hope this helps...
NB. You can see it in action over at
