You will need to use napigator alongside it to connect to a server. LimeWire is a Napster clone but allows any file to be transferred. It also allows multiple searches to coincide with one another. Napigator allows users to choose which napster server to log on to. This is handy if the mp3 you need is not in the server napster has assigned you.
Bear share is another multipurpose file sharing utility.
Wrapster is used along side napster and allows files other than mp3s to be downloaded, so programs, movies and documents are available to share.
