I listen to a lot of music. And something I do kind of unconsiously is connecting music to other things i like. So, because MGS occupies basically 80% of my brain, there's a lot of songs that remind me of different characters. Here's some of them, with links to Youtube uploads so you can listen yourself!
(I would eventually like to make the songs listenable on the site without having to link them.)
