This is a valid question for several reasons...
A person may not be experienced in playing for 'dances' and would like to know what people are playing for various types of gigs ... this is a question that has appeared here in many ways i.e. "what songs to play for: a Bar Mistvah; a NH; a 50's party; etc., etc.
Because a person may not have the EXPERIENCE in playing 'dances' does not mean he/she doesn't have the ABILITY to play those gigs and play them well ...
It is true that experience means a lot, but NO ONE starts out being experienced ...

And maybe the asker is just being inquisitive as to what people are playing for various types of gigs ...
JMHO,
