Thanks for posting that!
Loop-the-Loop was very... energetic, if nothing else. Didn't really stick with me yet, but it might do so after a few listens.
Raimei ga Naku Koro is okay. Nice to have a more peaceful track for a change, but it's not really the catchiest material either.
Overall, a mediocre single. hurr derp not really anything else to say.
... Well, there IS something else. I think it's time for the month's mini-poll: your favorite KOTOKO single tracks after Epsilon no Fune? Mine would be...
1.) Digital Smile
2.) BUCCANEER
3.) SCREW
4.) Raimei ga Naku Koro
5.) Loop-the-Loop
6.) Hekira no Ten e Sasoedo
