* song/artist/album repetition after a long pause

  After a long pause in the player, it becomes possible to add to the playlist
  a song that was played recently, even if it was added to the playlist
  sufficiently long ago.

  For example 'Song' by 'Artist' is added to the playlist. Then the player is
  paused for more than the 'min-album-interval'. At this point it is possible
  that a new song by 'Artist' is added to the playlist, which would cause
  artist repetition on playback.

  The fix would be to project song play moment and use that for the DB
  queries. That would require keeping player state, including the playlist.
  Also, song duration needs to be part of the database. Song last play time
  needs to be stored in DB.
