I tend to agree... Anything new and too 'stimulating' (e.g. Ligeti) my
brain will switch to "analytical listening mode'.
I have found any instrumental tonal music from the early baroque up to
Mozart (not all works and Beethoven onwards tends to distract me) very
good to help me concentrate and pleasurable at the same moment. I guess
it's the 'reassuring' and 'familiar' aspects of that kind of tonal music
which (like it or not) are now hard-coded in my brain.
But I also guess there's always a personal quid to it...
