Cover art for Old Soul lyrics by Great White Buffalo

'This is my roll' definitely sounds like it should be 'role' instead. But this is how it was posted on their website, and it's one of those things you just can't be too sure enough about to change.

What it's about? It sounds like it has lot to do with the reincarnation idea of an 'Old Soul'.

tl;dr Old Souls are souls hat have been reincarnated many times already and are nearing the end of their life cycle. They are often very tired and do not accomplish much in their individual lives. This usually stems from an attitude of having given up on the world.
