My english is probably not that good, but in Audiogalaxy you search for a specific user and when you have found it you can see a list of all the song that user has and then get hold of them.

In kazza and Grokster you search for a song and get a hit and then you can use a function "find more from same user" and you can see a list of all that user´s files. But if you don´t get a hit you are unable to see this list. My question is if there is a program where you can search for a specific username and then see a list of all that persons files. If you can see all the files from a persons folder by the function "find more from same user" why can´t you see them if you don´t first get a hit. By searching for the username for instanse.
