I can't seem to download any songs by a certain alt. country artist, who has a similar to the prominent Canadian soft rock singer of the theme to "Robin Hood". I keep getting the "Need More Sources" response, even if there are more than 30 users reportedly sharing the file. It's really very strange, because I have been able to download songs by other artists. Just not his. Is there a reason for this?

Try browsing hosts. This can help to get downlds to continue. So browse those that have songs from this artist. And then perhaps even browse those results if there's multiple results in the browse as they might be connected to others who may also have some songs by that artist or similar music.

It turns out that I just can't get songs from his latest album, which is fine as it's not supposed to be that good anyway. Thanks for your help.
