"Punk rock should mean freedom, playing whatever you want,
As sloppy as you want as long as it's good and it has passion" Kurt Cobain
I use to play Rock Band 3 all the time in the 1st year of release, but after that my guitar broke, so the only 2 instruments I can play are Pro Keys and Vocals. I don't play either of them nearly as much as I did with guitar.
I've pretty much migrated to Rock Band Blitz and play that mostly. It's fun to go back to my legacy dlc that I can't do anything except sing now.(Unless I wanna play guitar charts on a keyboard, but I don't find that fun)
There are quite a lot who still play it, just not the quickplay online thingie.
Friday night, 9-10pm (Middle Europe), and in 10 minutes I've only gotten 1 other guitar player, but he left after a couple of minutes, as he couldn't be arsed waiting for more (I guess). No drums or vocals. Can't remember the last time I had a vocals player with me, but it's 4 months at least.
If you can find friends and invite them, that's pretty much the only option.
It's spelled "Squier." Stop spelling it like someone who is in training to be a knight.
