Custom Reverse Buzzer

I've seen a few threads but can't find anything but backuptunes.com I am about to buy it but I feel a bit ripped off since you can't change the song for $80, you should be able to change the song!

I was excited and bought one of these with an amazon coupon that made it like $25. Sadly, it doesn't quite work the way you want, it plays the whole song every time you put it in reverse and takes a few seconds to load up. Since it's 3 wires instead of 2 there's not really a way to cut it off that I could figure out.

Does anyone know of anything else out there that can do the job of 2 wire reverse buzzer that plays MP3's instead of annoyingly buzzing? I'd love to be able to switch around songs sometimes to Star Wars or The Muppets or Benny Hill, or college fight song depending on the occasion.

I was looking at this as a horn. I'm not sure if would shut off when not in reverse right away or play the whole sound.

I watched the video on that one and it looks like it would play the whole song, I saw him hit the negative battery terminal to get it to stop. Thanks for the idea, I can look around more at horns vs strictly looking for a "reverse buzzer".

I added a trolley bell I found via this site for my horn. It's loud! It's cool too. This is that trolleybell, The guy said they have it hooked up as a reverse buzzer for their own carts but I like to be able to ding-ding vs just having a slow paced ding.
