When noodles was still very, very young and just producing their first album The Gravity Thief in 1995, one of their songs was used in a Coke commercial. The song became an instant hit, playing on radio stations all over Japan. I have reason to believe the song used was mellow metallica, but I have not found any confirmation. It's also very possible that they wrote a song or jingle specifically for the commercial, and it never appeared on any noodles releases.
If you have more information (confirmation of what song, a video of the commercial, or any thing else I can post) PLEASE email me at firstname.lastname@example.org! I will be forever in your debt ♥!
