Software to made playlist with BPM and harmonic

[lbarasc]

Do you know some tools (free or not) that make playlist of mp3.
I want the playlist sorted by BPM and, for each song, harmonic songs compatible.
Thank you.

I would try clicking the BPM tab in Serato & then highlight all the songs a drag and drop them to ListIt. You can even setup ListIt so it auto filters out songs or even parts of your artist or Title tag when creating the list. It has some cool features & its free. You can get it www.mixcityinc.com
