Like I said, Khan, I prefer to keep instrumental music for my playlists but I know a number of people who've included bands like Alestorm and a few others to have a more rocking playlist for their pirate games or games in general :) Hell, for kicks I went and through some Dragonforce at my players in an encounter or two when I ran some fights against robots in Numeria in a previous game.
Goddity, I went to PotC last because I knew I'd find a lot of stuff in there worthwhile from all their films. There's a number of those in those playlists already, including a large chunk from AC: Black Flag, Black Sails, the Uncharted series and some Risen 2. I'm always looking out for new stuff I possibly haven't heard of (or thought of). As a side note, just stumbled onto some music from a show called Davinci's Demons and...some of that stuff has me pretty floored. So stealing one for a major encounter in Cheliax. Had I only known for Hell's Rebels! If you've got any other suggestions, I'd be happy to hear them as well, but thanks for the input though.
Hope these playlists will be of use to some folks :D
