How to send music via bluetooth

[iWooz]

How can I send audio files to other phones (e.g. Android phones) via bluetooth?
This works without any problems on my 8yr old Windows Mobile device, but I haven't found this functionality on iOS yet. Do I need a special app for it?

Thanks

am sure not built-in for sure, it would has to be an app, if not JB.

Which app can do this?
