Regarding "thinking" about music ... I recently took up playing drums again after a 20 year hiatus. During those 20 years I was never able to stop tapping rhythms on things (to my own and everyone around me's great frustration). Every song I listened to I couldn't not imagine playing that drum track. That must have kept those neural pathways alive. Now that I'm finally playing again, I feel like I'm back to my previous levels, or even better, after just 3 months of playing 1x week. Having said that, there's also the 10,000 hours thing.
