^^ Yeah. Well, the album is still great IMO but It's not as fresh as I thought it would be because there's just too many ballads/slow songs. I guess it's kinda expected because it's a Korean album, plus it's from SM! They always make the singles/promoted songs up-beat tracks and the album tracks are always ballads... (see DBSK, BoA is kinda different, SNSD is half-half) Apparently, a lot of the songs are covers/sampling other songs also.
^ Yes, it's a cover.
