Background Music

Hi guys, i juz need to know whether or not it's possible to set a wave file to be playing in the background in Nokia Series 60 devices.. And also on top of a background sound, can i play another sound on key press while the background sound is still playing?

Thanks in advance!

com.nokia.mid.sound.Sound.getConcurrentSoundCount() return 1, so I think it does not support more than one sound sample in a time.
But as I know, some symbian applications can play multi sound samples concurrently(they have both background music and sound fx). Maybe they have their own code to mix sounds. But how should we do this while using J2ME?

Hope for reply...
