Here in south florida, ft. lauderdale area we have lots of arranger players doing assisted living, condos, dances and parties, ect..Probably 75 percent of nursing home players are arranger players. Some of us use a track every so often for unusual requests like uptown funk or iconic songs that have a very demanding background.
The Ipad karaoke people are here too but not as popular because of the ability of players to "fake" a song if we are able or to do a medley if people are dancing or stretch a song.
As always I always say If I can play it live and make it sound great I will. \
