Good for you. I do find it strange that your enjoyment for music has decreased. Music is typically from the heart and soul. However, I myself have had strange things occur. Most notably, when I do an 'intensive' over an entire evening I get extremely energized and do not wish to sleep, I also lose care of everything material and am driven to only continue meditation--everything else does not matter.
This is probably because we are going beyond the illusory self of the physical world and entering into the true, non-local Self which is beyond material desires. In this state of 'non-state' I begin to see events happen in more than one way--all at once. (multiple possibilities) Deep within, I KNOW. But every time my "conscious" or 'thinking mind' tries to figure it out it gets confused.

Strange stuff, I love it so...
