It would be great if track recommendations were based on an overall analysis of my catalog that was compared to other users. Maybe being able to discover and follow others too
This would give another alternative to crate digging, and may create a more social aspect. In addition this could be rewarded somehow.
This is another idea back from Rekordcloud 
But this idea really requires a lot of users and the ability to understand the users’ playlists and what they mean. And there is the privacy aspect, and since Lexicon is local only it’s not just possible to scan the library of all users.
This was (and is!) always a good idea but I kind of abandoned it with Lexicon since the library is not easily accessible anymore.
