I found it a while back, but it was not an mp3, it was an ogg file or something like that.
I think it is part of the "Home" app, the original launcher.
I replaced that app wih GoLauncherEX.
If you have a root file manager like Root Explorer, you can extract the launcher to SD and get at the file. It should be in the assests folder.
I prefer GoLauncher so much that I don't feel the need to fix the stock launcher.
I removed the app altogether.
