Since these come from the index reader we do not want to limit the selection to a heap since that would slow everything down. Instead we simply extend the current selection if the song satisfies all other criteria (in tempo, proper tag etc) we also do not check cache updates or the likes, this means that the filter must be applied in 2 steps. First to check the tag, then to check its distance to the main song
