Oh, and as a guess to what the title means, I think it may be referring to what one does outside of work, after his/her 9-5 "day job" from 5-9pm. A lot of bands struggling to make it have members that are forced to work full-time jobs just to pay the money that they put into the band. On the other hand, some 9-5ers go home, eat dinner, and veg out after getting home from their day jobs. The musicians continue to work.
