Has anyone else ever wondered what the music in Slugterra is like? is it almost identical to ours or is it like "listening to those remixes that are intentionally made to be bad but for them it's normal" kind of difference. Considering the technology Slugterra has I wouldn't be surprised if they had something similar to Vocaloid (at least in terms of the virtual idol concerts)
Either that or the Vocaloids are straight up real people in Slugterra
