I'm not a fan of the fact that half the great ER songs have no real meaning.
You're given an ancient language which you're obviously using and drawing inspiration from, yet you're unwilling to put it into practice at all?!!?
Look at what fucking Expedition 33 did.
Even if you don't speak French, all the songs have lyrics that make sense and are usually connected to the fight or person they play for, expanding on the lore in a way that a normal player might not catch but those that delve deep enough would.
All you had to do was write a few lyrics for gods sake. Everything else was already there...
