Artist names are now the same wherever you play a song from. Tracks played from an album page arrived with no artist at all, which meant a bare title in the player bar and no Last.fm scrobble, and songs played from a home shelf or an artist page carousel scrobbled things like "Aqua • 1.7B views" as the artist. Both are fixed, and the app now repairs a bad artist from YouTube's own data as the track starts, so entries recorded wrong before this release heal themselves as they play again. Thanks to the report in #4.
Artist names in the player bar are clickable for songs played from search, which previously lost their links on the way to the queue.
The player bar has an options menu next to the like and add buttons, with go to artist, go to album and shortcuts.
