The version of Romantic Summer on this CD is not totally rearranged like the momo-i version on her album, "Sunday Early Morning." It's just a solo version of the originally duet song. It even has a slightly better sound quality than the one on the single. That's a great start for a relatively cheap CD, isn't it?
It gets better, as other songs are very good, too, although some are a bit odd (track 6?).
Sound quality varies among songs, but they're generally pretty good. I'd say that the last track is the worst of them.
