I certainly do! Mean shift (https://spin.atomicobject.com/2015/05/26/mean-shift-clusteri...) is commonly used in image/volume segmentation, when you have CPU to burn. I've done a decent amount of work on optimization of it.

Actually I was curious enough about this novel use (and I happen to be interested in music myself, who isn't) I saw your post and thought about replicating it and emailing you results. I'd be more than happy to work with you on any non-commercial stuff. (An email address which works for me is on my HN profile, could you send me a note? Even if nothing else it doesn't make sense for all of us to spider/scrape the same datasets over and over...)
