Looks cool. Very similar to a service I built a few years ago: https://lanyard.fm which has setlist integration and even generated Spotify playlists of the setlist using live versions of tracks at one point. If you'd like to chat about any of the problems we faced let me know.

The site was never monetized, it was a side project between me and a couple of other guys. We struggled with data until it eventually dried up completely last year. To remedy that I've been working on a live music version of musicbrainz.org in my spare time although progress is slow. If anyone is interested in getting involved in that hit me up
