You should definitely check out more from tvxq/dbsk. Their live vocals are fantastic. The ballads they have are some of the best I have heard due to the very good harmonies they manage to do. Their up tempo is very good as well. From when all the members were together.
Quick post note I forgot to add in the video!!! Yes I am aware of that TVXQ and SHINEE are from the same company the only reference to Mirotic’s style was ring ding dong…so I’m saying it was not copying just had a similar feel
