My opinion on what Starbound themes would replace or be in Terraria themes. Each thing has a 13-to-24-seconds-long bit of the theme i said on it The slider on the bottom lets you skip through the video, only will skip after the song you are currently on is over. Also will switch to the number AFTER the one you set, so set it to one before what you wanted to set it to. Shortest Theme: Dungeon & Underground Corruption Theme (#9) - 13.04s Long Longest Theme: Underground Snow Theme (#12) - 24.49s Long
This is all my opinion, if you disagree with anything, then don't get mad at me. I think one of the best fits is the "Crystal Battle" theme for underground crimson & pillars... the underground crimson is very similar to the Ruin's surface in looks, which is where you hear the "Crystal Battle" theme. Also, it's good for the pillars, because the pillars is RIGHT before the final boss, just like the Ruin's surface. 10/22/2017: Added volume control! :D
