2nd Master Mode Song Unlocked

So last night I went back to Next Girl by The Black Keys.  On my 2nd time playing it I finally nailed the entire song and unlocked the master mode, which is where you can play the song with just the backing track, no notes on screen.  I haven't actually played it like this though, I want to run through it a few more times before taking my crutch away.  I'll just not look at the screen unless I get stuck.

I've also started trying to learn Crazy Train.  This is not a song in Rocksmith so I'm having to do it the old fashioned way with videos and tabs.  If I can learn to play everything (but the solo) by the end of the year I'd be a very happy man.  So far I can do the first 30 seconds or so at about 3/4 speed.
