im not saying play a full set of cheap thrills, but one classic might be just the right push if your trying to bring a bunch of people from the bar out to the floor. if it gets em dancin it gets em dancin.its not a cut and dry formula for instant success, but once in a great while i enjoy hearing a familiar song. as an opener your supposed to warm them up and get em out there. when you have an empty floor and an twenty minutes before the headliner goes on id be more concerned about getting them out there than worrying about people knowing that the song doesnt come out until next month.i understand what your saying and i agree and in some situations or places it could come off as desperate, but if there was ever a time for a classic or a trick wouldn't that be it? maybe you know from more experience and its a naive thought of mine, i dunno just throwing it out there. anyone agree...disagree?
