Hey all -

My wife is about to start running her first ever campaign (Rime of the Frost Maiden) after a few years of being strictly a player. She's really trying to do it up right, and is thinking about making a playlist of various music to have running in the background. To help her out, I've got two questions:

First - what's the best way to do this software-and-hardware-wise? She's got an iPad and phone, we've got our aging laptop; what apps do this work the smoothest? Keep in mind she's thinking of being able to switch from one playlist to another as situations change in-game.

Second - what are everyone's favorites when it comes to tracks? I was thinking of organizing things into three broad categories: combat, mysterious/suspenseful, and sort of innocuous, low-key background fantasy music for when nothing major is going on.

Thanks in advance for any suggestions!
