A friend of mine started using a music player and manager that can dynamically create playlists based on MP3 tags. He is happy with it, but the only thing missing for him (he works as a DJ sometimes) is the ability to automatically maintain all his songs BPM (beats per minute) information, and create those automatic playlists based on it.
As far as I've researched, the ID3v2 tag format allows BPM tagging, so the only thing missing here is getting another software that could automatically analyse a bunch of MP3 songs, identify their BPM's and tag their respective ID3v2 information accordingly. That being done, it would be very easy for him to play around and create his playlists.
I've made some research on it, and found some freeware and paid solutions. I'd just like to know if anyone has a great software suggestion for this.
- update MP3 tags to include BPM info extracted from the files, while not losing other information already existing in those tags
- run on Windows
- a GUI
- batch-mode to process "marked files/directories"
- free as in "free beer"
