For me, Evanescence led me to other such groups like Lacuna Coil, Within Temptation, Nightwish, Halestorm, and Delain. Found myself pimarily along the female vocalist path. There are far too many to list of course, due to the sheer number of them. Only album I've ever listened to in its entirety from Godsmack is Faceless. Of course, I did find myself listening to Linkin Park, System of a Down, Korn, Disturbed, and Static-X in between. Yes, I am kind of big on rock and metal, but I do have numerous other genres to keep my ears musically diverse.
Even though familiarity is always a reassuring thought, I think I could benefit from learning a few new things in taking a modern approach. That means I am counting on the nice helpful person you are to help me if I get myself stuck for some strange reason or another. But I think if we work through those moments, we got this covered.
I did originally watch Once Upon a Time on a weekly basis when the first season started, but fell behind after about seven episodes and never got a chance to catch up. I do have the first season on DVD, yet I haven't took to watching that either. One day I will, I just know it. That means there will be little influence of the actual series crossing over into this RP unless by coincidence. I do prefer your choice for Queen to that of the one in Once Upon a Time.
