Long time lurker of this thread so i decided to post for once. Very musically random as Animusic is not a band, its a company that was started by a software engineer who also created music on the side. The animation software at the time was never good enough so he wrote his own software program then created his own animated instruments to play his music.
The result was Animusic.
This is one of my favorites from the Animusic HD BluRay. I recommend playing it full screen for the best experience.
I'd objectively say 9/10...but I'll +1 subjectively.
As for my own...it's always very hard to pick one song when you love music so much and have very eclectic tastes (as in, sometimes "all over the place" to anything that takes my fancy).
Really struggling to pick, as Laleh - Tomorrow is also one I truly mellow out to...but I'll go for :
A "motivational" song for me, always a pick-me-up whenever I feel gloomoody (should be a word).
