To be honest, I've played for nearly four thousand hours. The Terraria music is as stale to me as a piece of bread buried with a mummy. I pull up youtube and pop in one of those 30 minute extensions. Megalovania (Undertale), Snowy Valak Mountain - Night (Xenoblade Chronicles), Throne of the God That Caused Everything (Tales of Zestiria), and Magikarp Festival (Pokken Tournament) are my current go-to tracks.
I never really did get tired of the Underground Corruption theme though. Sometimes I'll turn off the youtube music to turn on the Terraria music for old times' sake.
