Why Don't The Setlists Use Abbreviations?
The default Phish.net setlists avoid abbreviations, for maximum clarity and so as not to confuse newer fans. (Show notes and song notes do, however, use abbreviations.) This was done even in print, for the same reasons, despite the space that could have been saved. Sure, it is easy to deduce that “YEM” is the same as “You Enjoy Myself.” But not everyone would recognize PYITE, BBFCFM, MMGAMOIO, WMGGW, or SOAM - and SOAM might be :Scent of a Mule" or "Split Open and Melt".
