What is the advantages of free bird?

'Free Bird' is a lengthy yet popular song that radio audiences generally enjoy hearing every once in awhile. Due to its length, while it plays, a DJ can pull a day's music schedule from the station library, can make a lengthy trip to the'facilities' or can order a Pizza, wait for its delivery and get change from the driver for his $20 bill defore having to return to the console. That makes it a 'win' for all!
