I can definitely see how for big exclusives e.g. KPM it’s easy to handle, but yes, those smaller exclusives who aim more at the hobbyist
youtube contentID works perfectly for exclusives, big or small.
The thing that many composers, music libraries and AdRev don’t realize (I think AdRev does actually realize it but they don’t advertise it) is that you HAVE to have exclusive rights to the music to even upload it to youtube contentID.
ContentID and AdRev and every other middleman out there works perfectly if you are exclusive to one company.
Non-exclusive libraries cannot use the youtube contentID services because you HAVE to have exclusive rights.
That is the only issue here. Non-exclusive libraries uploading and pretending they have exclusive rights just to earn a few pennies (and most often without the knowledge or remuneration to the composer who owns the music).
