MusicBee is one PC alternative I've tried but I can't say I was a big fan. Google Play Music is another to check out - what's handy with this is you can upload your collection and access it from any device as well as stream like Spotify. Has its fair share of problems (shit-tier organization), but I think you've got to take the bad with the good when it comes to music players. No one's made an end all be all yet.

You should post your monthly playlist as a blog entry! Always love to see some new tunes.
