I was wondering if anybody knew of a good setup/app/whatever to accomplish my goal.

I would love it if my phone could be playing music, receive a message, and play the alert (or some alert), OVER, along with, at the same time.

As of now, unless the phone's sound is off, it stops the music for a second, plays the alert sound, and continues the music.

Has anybody found a way to get an alert sound, without stopping the music?

thank you in advance
