All my songs are named like <Track#> - <Title> - <Artist> (I am not letting iTunes manage my music). But now I discovered about 60 songs which aren't named like that. So, I was about to rename them to the correct pattern, but I was thinking: when I rename them, iTunes won't know where the songs have gone and can't play them anymore. The easy way to fix this is by deleting every song from the library, rename them, and insert them again. However, I want to keep the song data (play count, skip count, in which playlists the songs are), so deleting them from iTunes isn't the way to solve this for me. But what is the way to rename tracks in my iTunes library without losing the track data ?
