YouTube Music Algo Updated?

Looks like something changed w/ the algo recently. Topic videos seemed to get a sudden jump in suggested views. This is good because @YouTubeMusic pays almost 2x Spotify does (unless you're @WaterflameMusic on @Tunecore, which takes a 20% cut for YT).

For Autodidactic, it was extremely noticeable since the channel is smaller and its topic videos generally had zero view count before a sudden jump:



But even Waterflame noticed it because his top 10 videos suddenly included a YT-Music topic video that was never there before.
