First off, I am going to leave hip hop off the list. Just too much to try to sort through otherwise.
These are songs I discovered this year. It does not mean they were necessarily released this year, although a good deal are in fact new.
In no particular order and with no justification other than I loved em:
Sharon Von Etten
The Flying Stars of Brooklyn NY
A House In The Trees
Durand Jones & The Indications
Merry Christmas. Enjoy.
