I used to use Predixis Magic Mixer. It will perform a brief analysis of the audio in a file, produce a "finger print" and compared it to fingerprints in a central database. If listed, it would set an identification code which is the result of the analysis of the entire file into the client copy. If not, it would do a full analysis on the client computer (takes a while) and upload that to the central database and keep the local copy as well. From that information it can set up a play list that relates tunes, one to another' depending upon the actual sounds. I have not used it for a few years so I don't know if the central database servers still are in operation, but a web search says no. It should still work, but every file will require full analysis.
