Without looking into the old and outdated source code, my guess is that it’s related to improper handling of the sound complete event that is dispatched when sound data is loaded.

I’ve replaced the playback component with the Playr API that is more feature rich and complete.

See if you can use the latest version: Flex MusicPlayer v.2 with MusicVisualizer

I did notice one issue (if you want to call it that). If you begin to play before the song is completely downloaded, the player resets (stops playing) when the trackslider is complete. In other words, if I begin to play immediately on load, the player stops at about 10-20 seconds into the song – I can the hit play again to continue.

Any advice on how to stop this from happening?

Thanks much.

I added support for multiple tracks with the Prev./Next track buttons, enabled track scrubbing, replaced the playback component with the Playr, and added the music Visualizr from Ronny Welter

A more extensive example with a playlist, cleaned-up source code, and a sample of pulling music from last.fm will be posted soon.
