MAJOR TOPICS for Upload/Download HELP
Unfortunately the gnutella network is being flooded with spammers in an attempt to prevent copyright sharing.
There are different types of audio fake files. One type of audio file, be it an mp3, mp4 or wma is actually a virus program masquerading as audio files.
Another kind of audio fakes are files that have deliberately been made corrupted. Their file size does not match their bit rate. There's also another kind of spam where you get recordings of clinton. If you hover your cursor over an mp3 in your search results and it does not show any tag information, then there's a high chance it is a fake. Some fakes do have tags but with minimal information, in which case check the file size and the bit rate as suggested above.
Stay away from audio files that are less than 2,000 KB (2 MB) in size. But also stay away from a couple other sizes that are spammed. Here's a post with example file sizes:

The problem with iTunes is it has changed its library sharing technology slightly. LW will eventually be changing to it. But you can still use iTunes without it.
Files shown already downloaded in the LW LIbrary window, those that show in the Saved Files folder, will not show in the Shared folder unless they are shared files.

So you can right-click them & choose to share file.
