I think the answer to this varies on certain factors
Can you use it on a future dead musician and choose to simply save the opportunity?
If you pick someone who died a long time ago like Kurt Cobain , do they come back in 2011 or does history just re-write as if they never died at all? (And then if they come back do they come back with a changed attitude or would he just RE-kill himself AGAIN? lol)
If you pick someone will they and their fans know you're responsible for the miracle? Could you perhaps bribe the rich families friends and/or fans of the musician and just ressurect the highest bidder?
Or is it like , you rez them they come back to right now you don't get paid and nobody will ever know you're responsible for the miracle?
I mean if you could save it for a future dead musician I'd definantley consider waiting and seeing for a bit or maybe loopholing it to rez people I actually personally know if they died and just argue that they did play an instrument lol
If you could get paid for doing so though I think I'd have to go to the Jacksons and say "Look , I can rez Michael buts its gonna cost you like $20million dollars , that cool with you guys?" (Why wouldn't it be? I'm sure their rolling in cash between Michael being the highest album sales artist of all time , Janets career , and the Jackson 5 , plus the fact MJ owned rights to the beatles music) so if that was the case then just pick him
If however they are none of these special circumstances and whoever you pick just gets brought back to right now and you don't get paid and you can't save the chance etc. Well then I'd have to go with Jimmy "The Rev" Sullivan from A7X
