LimeWire Seems To Help Find These (Score 2, Interesting)

I don't know about other P2P programs, but LimeWire has told me on many occasions that it has detected file corruption and asks if I'd like to continue to download. I don't know the process it uses, but it is probably some MD5-type checking. For audio files, it indicates the bitrate so I only download files that specifically indicate they have at least a 128 bitrate.
