Do you normally have a DJ at the e-party???

Hi girls, maybe you all can help as I am clueless to e-party do's and dont's.

My parents are being great and have offered to throw us an e-party... but I am not sure if we should have a DJ. Here is the specifics... it will be at a restaurant in a pvt room on either a Fri or Sat night. There will be about 60-80 ppl.

I just don't want it to be boring but not sure if I want a DJ... PLEASE HELP!

TIA
