So I have a folder with 12k+ songs that were from my old computer and when I was only a kid and didn't know how to keep music in a good filing system and its just a whole folder with just music file and a lot are untagged. From my searches through here I found MusicBrainz Picard as the best tagging software for me and this task, it added the tags.

​

I then create a playlist on Windows Media Player and save all of these now tagged music files to it. Load in a large hard drive to sync to then sync and it creates a decent file hierarchy on the hard dive with albums and artists all separated. Then add this new library on the hard drive as your main library in Windows Media player and let it add info to the files but not overwrite.

​

This has saved me an immeasurable amount of time but it still takes days to get through even with a half decent computer. 32GB Ram, 8 core Ryzen buts its the slow 4TB HDD I am working off of that is bottlenecking me at the moment. I went from having only one folder for these files to 1000+ that are labelled in the correct artists and albums (mostly, it's not perfect).

​

Thanks community I've always hoped I could eventually do this to my old music.
