PUID duplicates

I have a quick question about puid's. If Beatunes finds multiples of songs with the same PUID, are they definitely exact duplicates of the same song? Could they be different versions of the same song (eg an album version, radio edit or remix) or even different songs altogether.

If I do get 2 songs with the same PUID, can I assume that they are the same song? If they aren't labeled as the same song, can I assume one is mislabeled? Is there an easy way to listen to these songs in the analysis window to hear which version I would like to keep, and which I would like to keep? If there isn't an option to do this, can I request this feature? If this is to hard to implement, can I request the ability to save a list of these songs to a playlist, or similar, to check them after analysis?

How is the PUID selected? online search of song title? song analysis? or is there an option so select teh PUID generation method? Can the PUID be changed if it is allocated incorrectly?

    Hi Chris,

    PUIDs as generated by AmplifiedMusicService/MusicIP are not necessarily unique. I'd say they are pretty much unique, but so called collisions are definitely possible. That said, they are relatively improbable.

    In the end the same PUID can correspond to two songs that are just very slightly different or two songs that are completely different - but as I said, it's improbable.

    So, if you want to be 100% certain, that two songs are different, you will need to listen to them or look at other data, like duration etc.

    Yes, the ability to listen to a song in the inspection is currently missing - however, it's already implemented and will be part of the next update (i.e. v2.1.4).

    MusicIP PUID creation is based on acoustical fingerprinting. Values are submitted to an online database by users (http://en.wikipedia.org/wiki/Portable_Unique_IDentifier).

    Hope this answers your questions!
