Thanks!
I actually have an artist in my sights who has a lot of decent quality music available with a fantasy twist (https://www.youtube.com/channel/UCG46uU4jlxak8DvmcVqN2oQ) and is willing to share her music for free. I like a good number of these tracks and can already see some of them in particular areas of the game.
I just need to sort out the engine (sounds work well, but the entire "music player" part seems very wonky and doesn't like any music files I throw at it, might end up writing my own player) and some of my internet issues (forced to work with low-transfer-limit LTE connection instead of broadband, can't stream much with that :/).
But music definitely is coming soon-ish.
