Hi Mark - first off, thanks so much for the kind words, and we're so glad you are digging the lessons on GT!

I have to say - you made me LOL with your experience working on songs with all the parts continuously running through your head. This is exactly what I experience leading up to when I film my song tutorials. Sometimes I'll wake up in a cold sweat in the middle of the night, playing a guitar part over and over in my dreams haha.

I have a few suggestions for you to try and shake things up.

First up - you might consider using 30-60 mins of your daily playing time practicing exercises and drills that aim to tighten your skills. Instead of burning out on song parts being played over and over, perhaps take some time to work on your picking, timing, strumming, and chord changes in a more general sense. Start slow, use a metronome, and simply drill the basic mechanics of your playing skills every day. You can find some drills and exercises to get you going here:

However - I just want to stress that you should NEVER stop learning songs!! I am suggesting this approach as a companion to what you are already doing.

Next - when you're working on songs, use the speed buttons on the side of the video frame to slow down the song. This allows you to focus more on smooth execution of the parts instead of blowing through the song sloppily. Try 50%, 75%, or 90%, and figure out the sweet spot of where you can play through the song smoothly, without any mistakes, and then STAY THERE! Lots of repetition at this slower tempo will force you to focus on smoothness and dexterity. This is a more efficient and effective way to practice, and you should start seeing progress in the tightness of your playing quicker than what you're doing now.

I hope this gives you some ideas to try. Let me know how it goes!!!
