As I was a little bit bored, I decided to extract the gacha music and try to work-out the lyrics.

Some of the lines aren't the easiest to understand, but here's what I got and am fairly confident on:

Yeah, the shining gold aside,

let your inner - spark ignite,

find a treasure - glowing bright,

richer for it and taking flight,

lucky or not, at least you tried,

chin up, in yourself confide,

no doubt fate's on your side,

you're chosen, so enjoy the ride!

There're things you can't control,

fortune's fickle, that's just wrong,

embrace the result, stop keeping score,

that's the essence, life's true goal!

Not just trials, battles tough,

go take enjoy(ment) in simple stuff,

even when it's getting rough,

take it easy, having fun is just enough!

Edit: I've been told the first line could possibly be "Yeah, the shiny gold design,"
