garbled mp3s

I find a lot of the mp3s I download are nothing more than this strange rhythmic static sound. Sometimes those kind give me a message about corruption, and I don't bother downloading them, but sometimes LimeWire doesn't seem to catch them. Anyway, I'm just wondering what causes them to sound that way? I've had files from many different sources that all end up sounding exactly the same way. Even files with a good rating, that several people seem to have, and which are the exact length of the real song. Has anyone else come upon this problem?

You're probably trying to play them through LW, right? I don't recommend it. Find them in your computer (they're in a folder called Shared) and play them like you usually would play a music file (meaning not through LW)

I get that too. During a song after the first minute and every 22 seconds after that I hear this rythm type sound. I use Windows Media Player to try it and it still does the same thing. It gets annoying and it never happened before so why does this happen?

I might have a different problem. Can someone help me?
