YouTube doesn’t care how many viewers there are for a work – that’s not a factor.
YouTube has some very sophisticated algorithms, and they are able to detect a different performance of a work on some occasions. This tends towards false positives (Stavinsky’s* Rite of Spring* performed by the Moscow Symnphony isn’t the same performance as the work performed by the London Symphony, but YouTube doesn’t know the difference and may serve up a copyright strike if not challenged).
I have challenged such claims where I knew I could win (and I always do), but it would be a bad idea to dispute one if you can’t back your bluff up.
So beware. Sound analysis has improved much over the past 40 years, especially if there is money or vindictiveness behind it.
If distributing your video is the primary objective, you might consider Vimeo or other Internet video sites who have different policies, or post it on your own server and hope for the best. Vimeo has accepted some videos of mine that YouTube rejected for copyright reasons.
