I don't really see why it would take months to fix the tags on your files - perhaps if you were introducing new tags like "length of lead singer's hair at time of recording" then the process might be a bit messy, but you'll find that the important data (artist, album, song, year, genre) is already available and easily accessible in teh internets. For a long time I didn't bother with tags either, then I started using Music IP mixer as I realised that I had tonnes of music on my server that I wasn't hearing because I was simply choosing stuff out of habit. Music IP mixer requires your music to be tagged so that it can create playlists of music that are similar or linked. The process of tagging the files took a couple of afternoons, but then this was on my main media server and there is a hell of a lot of stuff on there.


TLDR - tagging is worth the effort
