I've figured out how to make my shared folder automatically send the downloaded songs into iTunes, but I have a question.

Do I really need to THEN convert each file to Apple's proprietary format, AAC? It takes forever to make the conversion on each song. And, furthermore, it scatters the downloaded songs so I have to look for them and then convert. It's very messy.

Do I have to go through the conversion process at all. Can I just download from Limewire (automatically imported into iTunes) and sync them directly to my ipod?
