iPod:1,500 songs in search of their metadata

[ChrisM666]

This question probably has an obvious answer but my ignorance Apple-wise is still great.

Question:
I now have rescued 1522 songs, named but without artist, album and genre info. Is it possible to obtain this info from some source on the Web to flesh the tracks out once they're back in iTunes or before? I can't use the iPod or the iTunes it is supposed to be married to.

Background:
I have an iTunes with no tracks in it - all removed by the owner after recording to save HDD space - and an iPod full of tracks recorded as WAV files (35MB a track!!). After a disaster screwed the iPod and I had to rebuild the tracks' file names with blood, sweat and a hacked-about iTunesDB. The missing metadata had to be sacrificed to get the song names.

I have converted them to M4A tracks and shrunk them to < 10% of their original size. I am hoping/guessing that this will also give the files a data structure to store their metadata in (if it works like that).

Can I get this information?
