Artist names are the artist again. A search row that leads with its result type was handing the whole descriptor down as the artist, and queue rows did the same with their byline, so the wrong text showed up on the track and got scrobbled with it. Both now take the artist field alone.
Local music stays out of On Repeat. That playlist is built from what you play on YouTube Music, so files on your own disk no longer count toward it, and any that already did are cleared out. Local songs also drop the "Go to album" option from their menu, since the album they belong to is a folder, not a page.
