A sometimes snide remark cast at a crappy band, in an attempt for them to realize they should play better music.
Also used by the dude in the crowd who wants to break the bands silent song transitions, some may say a hero.
(Band quits entertaining) : dude in crowd who likes to have a good time - âPlay free birdâ
Person who actually likes the band but is also hilarious and enjoys unneeded attention: âplay freebirdâ you fucks, cheers bitches
