I think it's ok to include B-sides in an album but there should be a limit , maybe about 1-2 ?
not like 4 in Mika Nakashima's upcoming new album VOICE
& when you include 5 A-sides , 1 digital song in an album which only leaves 4 new songs it's quite meh
I'm curious to know how Megumi no Ame will fare in time to come
