Twinbee isn't a series where I can just quickly identify the game when I hear the music. I spent some time making comparisons and made a small update to GMR:

http://www.gmronline.com/info.asp?CatNumber=KICA-7677

From what I've been able to determine...

1. [Detana!! Twinbee]
2. [Twinbee Yahoo!]
3. ??
4. [Pop'n Twinbee]
5. ??
6. [Pop'n Twinbee]
7. ??
8. [Detana!! Twinbee]
9. [Twinbee Yahoo!] (I'm fairly sure)
10. ??

I just need someone to identify tracks 3, 5, 7, and 10. Thanks!

According to http://www.music.ne.jp/~konami/cd/1995tm.html:

3). Pop'n Twinbee
5). Twinbee ~Rainbow Bell Adventure~
7). Twinbee ~Rainbow Bell Adventure~

The info for track 10 doesn't give a game name, but "Song: Pastel (Hekiru Shiina)." Shiina is the vocalist, and Pastel is a Twinbee character, so I'd assume the song is supposed to be "sung" by Pastel. It looks like that song is either the same as or an arrangement of track 5 from KICA-7899 (fah at "ganbaresh" instead of "ganbatte" at least), which judging by this review might be from Twinbee Paradise, the CD drama. I haven't listened to Twinbee Paradise Sound Fantasia or any of the drama albums, though, so I can't verify that one.

Small note:  I believe it's "Yahho!" instead of "Yahoo!"

The music.ne.jp page CHz linked to is correct apart from one thing; track 9 is actually from 'Twinbee Paradise', the animation. And track 10 was made for the 10th Anniversary of Twinbee, so it's an original song.

Also, as Crash said, it should really be Yahho! instead of Yahoo!

Erasing a double post. Never mind this one.

That clears up a few mysteries, but what does 'yahho' mean? What about 'detana'? I checked the kana chart and 'yahho' could be a Japanese word (because of consonant doubling). Someone in the past told me it just meant 'yahoo', but now I'm not so sure. If it meant 'yahoo', the romanization would reflect that pronunciation (yahhu, for instance). But this is just a guess.

The problem with this is that, as far as I know, the Japanese alphabet does not technically have a "hu"; it gets modified to "fu" instead.  So, "Yahho!" may be the closest they could come to replicating the sound of "Yahoo!"

I'll bet that "yahho" is a bad translation (one way or another) of "yahoo". Kind of like how one of the songs on internal section is called "Chach 22", when the spelling is meant to be "Catch". Same with "what gose up". Man, that album is full of bad Engrish.
