What do the exclamation marks in the request queue mean?
The exclamation marks (!) in the request queue indicate a song that is in the queue and is inelligible to play for reasons other than the number of requests it has received. To play, a song must have enough requests and must meet the “diversity requirements”. See the queue help. Click on the ! mark to see details, this will display a message like: “This track can not play because a track by Iron Maiden has played in the last 8 hours. A track from Iron Maiden can play in 3 hours.”. When the track limit (the longest) has expired then the album and then the artist limit kicks in.
