What happened To The Profile Sound Player

I don't know where the profile sound player is or how to activate it in d7b4. Is it not included in this version compared to 6?

If I have a band that signs up and adds music, others would like to put their music on their profile page. Can we make that happen?

Perhaps while browsing sounds, have a + sign to "add this sound to my profile" option.

There is no audio player with playlist anymore.

It is possible to play one audio at a time.

But how does someone add music to their profile page?
