I think in this, as with many things, it is impossible (or pointless) to generalise.
In the last 10 years I've heard "Rolling down to old Maui" 4 times in different clubs, never once by the same performer. (and incorporated some different verses into my copy!)
Any other repeated songs tend to be when I visit a regular haunt and someone trots out one of their favourites periodically.
Otherwise there is little repetition, or none so much that it grates!

Cheers
