hmmm....decisions decisions.

option 1:
rock up to the club with pre-analysed tracks on USB keys. plug into CDJs. rock the crowd.

option 2:
rock up to the club with an S8. plus a laptop. plus cabling and and anything else you might need to plug into the sound system. potentially do all of this in the dark. worry about your kit getting messed up/stolen etc. convicing promoters/club management to let you do this mid set if you are playing after someone.

i think i know which option i'd be leaning towards.
