idk, at times i think singles are better than albums,
especially when it comes to JE. JE albums have some terrible filler tracks, like KinKi Kids' "F Album" LOL. not just KinKi Kids though, other JE groups got stuck with those too.
so yeah, i don't regret my JE single purchases at all. i actually like all the first press bonuses on the singles more than the album ones.
