CID isn’t accurate it all:
- it only registers tracks which are minimum 30 sec long
- it doesn’t register percussive tracks, remixes, ambient, tracks with 3rd party loops, etc.
- it’s very inaccurate
- it’s very vague
- it used to be a chain between Youtube and PRO by tracking music and sending data to PRO just to allow them collecting PRO royalties. In fact it works horribly inefficient, I haven’t seen any Youtube PRO royalties so far.
- (edit: this point has been removed due to lack of information and unclear AdRev instructions)
So in my opinion existing CID should be totally annihilated and exchanged with a really working system. IMHO current Google CID is a temporary dummy system which was made to 1. delay works on a more efficient CID 2. make a step ahead of EU institutions by saying “we already have CID” 3. cool down authors, PROs and goverments demands 4. earn a lot of money during that delay.
