> Thanks for that, but the referenced article is nearly 10 years old, the legal landscape has changed several times since Sync license requirements haven't changed and YT has nothing to with that. You're mixing up several things here and that might be where a lot of the confusion comes from. The songs you've uploaded might have been covered (pardon the pun) by YT's Music Policies, which consists of a list of songs that YT has license agreements for. In such cases, ad revenue handling, etc. is done automatically and you don't require a license. In other cases, however, it's solely under the discretion of the copyright owner to just grant you the license for free (i.e. they don't care), or demanding the content to be taken down, because a sync license would be thousands of dollars if not more. This is independent from any content ID practices, which usually only apply to master recordings (e.g. original songs or bootlegs). Copyright law is a complex (and IMHO messed up) topic, but we just don't have enough information here.
