God i've not been on here in a while.
I use foobar2k (columns ui, audioscrobbler with binds all over the place) for windows, and MPC-HC for my videos. Linux I used some terminal based player and Banshee, but banshee was pretty buggy I thought.
I used to use VLC but I found it bloaty at times, MPC is brilliant for everything I need to watch (with H264 codecs).
Also, just got asked why ripster is a 'girl version of harry potter' by a class mate.
