I need to get more sources, whatever they are, because I've been trying to get more songs and it says I need more sources. This is really frusterating, because I've been researching everywhere and everything is so confusing!

I want to go back to iTunes but I hate paying money.

Also, how to I get my host to by my iPod?

I really appreciate your help, because I'm really stuck, lost, and confused.

A source is a host (someone's computer) who has the file you're looking for.
Do your files sit connecting for ages & then show 'need more sources' without ever actually connecting? If that's the case, you're probably trying to download fake files.
Search again, vary your search terms, try the All Types search. Stay away from files with lots of sources, go for a file with 10 sources or less, or those with a modem source.

For movies, always check a file before download with Bitzi. A file with heaps of sources but no Bitzi rating is often a fake.
