I am a DJ but feel uncertain whether or not I can do 18th birthday parties because I don’t know what type of music they would expect:
A) Mainstream Top 40 hits (which I am capable of, as long as I frequently listen to Kiss 100 and the chart show).
B) Underground dance music that didn’t enter a mainstream chart (which I am not capable of cos you only hear that stuff in clubs and I am under age).
My natural instinct goes with B but I have my doubts.

Actually, it probably the first one, but generally it’s whatever they request as you should discuss this with your clients.
