MP3 to AAC difference?

I have an itunes library which has 1084 songs all mp3, would there be any benefit in converting all of them to AAC? Would there be any difference in quality?

Thanks =]

Nope. If you are importing from CD, it is generally considered that AAC is slightly better sounding than MP3, but converting MP3 is a big no no. You are basically creating a transcode, which is always bad.
Basically taking a compressed format and re-compressing it to another in other words.

Kev makes it sound like its illegal or something.

You can certainly convert the files if you wish, but there's no advantage to doing so, and as Kev says re-compressing just causes more quality loss. Just leave the MP3s as they are (or re-rip them from CD if you like).
