I have gained the impression that YouTube has two distinct techniques within Content ID, one for claiming melodies, and another for claiming specific recordings.

I’m absolutely confident that this is doing melody matching: these recordings are trivially distinguishable from any professional performance, with completely different instruments and playing styles, and with much lower quality singing.

For example, the most repeated claim was by “AdRev Publishing”, claiming “Crimond (The Lord's My Shepherd) - FirstCom” three times. (That song was also claimed once by “Capitol CMG Publishing and Adorando Brazil” as “The Lord's My Shepherd I'll Not Want”.) The first two times, I was accompanying with a piano-sound keyboard in the traditional four-part harmony—admittedly they sound fairly similar to one another; but in the third, an Indian was playing, using a piano-and-strings sound on a different keyboard, using Indian harmonisation (which is quite different).

I think we even had an unaccompanied song claimed once, matching throwaway0b1’s report.

These are completely different performances from whatever recordings the liars may have provided to the Content ID system. The melody is the only thing they will have in common.

My experience aligns with yours. I had a video of a half-hour coffee-shop-style gig blocked because at one point I covered "Hotel California". This was just me -- one voice, one acoustic guitar played poorly, and was down a whole step from the original key.

I believe that Hotel California is still under protection as a melody, rather than a performance. Hence covers require either a license or fair use according to law. This differs a lot from the case of performing a 200 year old song whose melody is in the public domain.

Not to say it was wrong what you did, or that Google was in the right for flagging. But Google was legally correct.

(Google suggests controversy around the question of whether hotel California is public domain or not)
