Yea, the combo of not so upbeat lyrics over a upbeat song is a pretty stable thing in a lot of Finnish pop music, especially older stuff.
This track is pretty good example of that, with the music being pretty upbeat/cheery, but the lyrics are about a young person who wishes to be a race car driver, but keeps driving recklessly and crashing multiple times and somehow surviving, but in the end of the song collides with a truck on the freeway for the final time (either dies or gets paralyzed after that, the wording is a bit ambiguous).
Glad you liked it!
