Looking for mp3 song previewer program Options

[gcapp]

I am new to this forum and I am hoping someone can point me in the right direction.

I have around 2 terabytes of mp3's. Somehow a lot of the files (random ones) got messed up. Some of the mp3 files play a different part of another song, then the correct part. I need to find these messed up songs and re-download them. But I have way too many songs to go through one-by-one to see if they are messed up.

So I am trying to find a program that will allow me to preview multiple mp3 songs (like 30 seconds or less). The same type of program that Amazon or iTunes use when you go to their stores and preview albums. They allow you to listen to 30 seconds of each song on that album.

I have looked everywhere and cannot find one. If anyone out there knows where I can purchase or download for free this type of program, I would appreciate the advice.

Thank you!
