Task for me: Produce the most unimaginative and "calculated" song EVER. Goal: To prove that points 1-4 are no guarantee for success and that creativity is valued in an experimental sense.
1. take the most famous of all chord sequences, which always guarantees success: C - G - Am - F
2. use the instruments that appear in the most popular library songs Simple 4/4 beat, a bit of guitar, piano, xylophone, marimba, high strings, clapping, ...
3. repeat everything over and over again, no too much ups and downs, so you can use it as a continuous loop
4. use a title with lots of happy words, even if they don't make sense, "total" is always great because it enhances everything afterwards, "happy" stands for total happiness, "up" is always better than "down" and "sunny" is something people like because the sun is our life-giver.
The song was produced after about 3 hours and is still not out of the sales charts. Unfortunately I lost the bet against me. Sad realization until today: Conceptual music always sells better than experimental ventures.
So when I take a pile in the toilet in the morning, totally sleepy, it's more creative than this one song :)
