Pretty good overall

A very good front end for Google Music on OSX with a few strange UI choices. The search function is very fast if you know what you are looking for, but it is a pain to use when browing your library. There is no way to filter by artist and then album and you are left to filter by artist and then sort by album. Unfortunately this usually puts all of the tracks in the wrong order, so even this isn’t a great solution.
It really is close to being an amazing player, because everything else works great. It just doesn’t have the browsing UI quite figured out yet.
