Don't add up amps, it's not the way its done. I count 5 circuits for audio, one for lights and one for AC. Usually you assign 360 VA (watts) to each receptacle plus air conditioning plus lights. The AC (11 amps at 240 volts) is 2,640 VA. The lights are 1,500 watts at most. That adds up to 5x360 + 2,660 + 1500 VA = 6,000 VA. That's only 25 amps because you're bringing in 240 Volts to the subpanel. You're barely going to draw half that under normal circumstances.
Even if you maxed out all circuits at 1,800 VA per dedicated line, that's still (5x1800+2640+1500)/240 or 55 amps at the ridiculous most you can possibly plug into.
Use a 100 amp subpanel with a 60-amp main breaker. At the main panel in the house, pop in a 2-pole 60-amp breaker and run the appropriate wire size (use 100-amp #2 wire @ 60 C) with the appropriate feeders, mind your grounding, and you'll be fine.
Inside, use 20-amp breakers for the receptacle circuits, 15-amp for the lighting circuit and check the manufacturers literature for the maximum breaker size for the AC unit (important at 240 volts).
Finally, put trust only in your electrician. Good luck and have fun towards your new project.
BTW - you'll have enough power this way for a well-stocked woodworking shop. Would add a ton of value to your house.
