The only way to recover is to clear the pairing list on the earbuds and start the whole pairing process over.

An example of a smart list would be "play tracks that have 'blues' in the genre and contain the word 'Baby' or 'Nighttime' in the title and are dated after 2012".After trying to get the manufacturer to respond about this I gave up

UPDATE #1: If a song is in a playlist and also in the favorites collection and I delete that song directly from the player's folder list, it does indeed get removed from the favorites list

Well the list must be to large for the AP60 because when i try to play that list it just reboots.
