If you find the Radio function getting stuck on a particular album, you can ban it by clicking favourite (heart) twice. This can free up the algorithm resulting in a broader selection.
In Album view, each track has a number of icons in a row. The "3 dots"one (to the right of the “favourite heart” ) gives quick access to editing tags and adding to playlists.
Tags are very useful eg. User defined tag 5*, 4* etc allow powerful filtering in Tracks view using focus.
