There are FOSS tools (in Ubuntu "bpm-tag" for example) that can do this, and I seem to recall mp3 tag v2.3 and later has BPM in their "extended" tags. This would be great for anyone who wants to listen to music while running, as playlists by BPM are actually really helpful in keeping tempo. Slightly niche, I know, but possible competitive advantage for bliss! ;)
