Also see Importing songs into iPod & iTunes for when you download new songs.

Within iTunes, to change the id tag info select the song & hold down Ctrl & i & a box will show where you can add the info. The library will automatically update after changes & files & folders will be adjusted. So don't move folders around manually. Also, if you're encoding new songs, select all those that belong to the one album by holding down the SHIFT key. Once selected, hold down Control & i keys & add album name, artist, year, total track no.s, etc. After that you can name them individually by selecting them one by one. It saves a lot of time. Also no need to put a no. in front of the song b/c if track no. is entered then iTunes will arrange them by that no.

(As a very late note, you can go to iTunes menu Advanced & select Get Track Names which will fill in all the gaps if you have an entire album & are missing some details. For advanced set-top players, they will also read this cd text info if your burner supports it & you select this option for cd-text.)
