From TM Wiki

Question for any editors: Are the TMO and TMN songs original works? If not please provide artist name in talk page. Also, someone find out the song names for the tracks with artist-only titles. ===PsYchOsIs=== 12:03, 5 September 2006 (CEST)

The music in TMN is not original. I don't know about TMO, because I don't own it. I would suggest checking the credits in the back of the manual. That's where I got the information currently in the article. ;) Dork 12:00, 12 September 2006 (CEST)

I thought "Doo" created original music for trackmania nations, and for trackmania original , you'd just have to contact nadeo if they still know any background history about it. the site of doo is doomusic.com
