I couldn't find your list of 200 but I don't understand why you would expect to be 'in touch' ... if you hadn't spent the year seeking out and listening to at least some new music.
Alternatively, you could say to yoursef, let's listen to some stuff from this list that I am not familiar with. Perhaps I'll even like some of it.
My method is to get my 25 year old son to do me a list every Christmas of newer bands/artists to listen to. Sometimes they are not so new. Here's some from his list this Xmas ...
Pastor T.L. Barrett
Makaya McCraven
Mick Jenkins
Sampa the Great
Sudan Archives
Oshun
Children of Zeus
Tirzah
Yves Tumor
Neneh Cherry
GAIKA
Eli Keszler
Khruangbin
... I hadn't heard of any of them, except Neneh Cherry, but I am working on it now.
