Hi,
In my opinion, in Sports and Training Goals the arrangement is too static. It’s 3:30 long, and in the first minute we already get the full peak of the events, which leaves no room for further progression. I know this is supposed to be background music, but with this length I think you need to deliver some progression and a bridge or breakdown part maybe.
In Modern Contemplation and Wonder I didn’t like the hats and the claps, for me they sound “programmed” and brittle. Plus the synth coming in at 3:05 sounds kind of 80s. But these are objective points, a matter of taste. I can’t tell for sure the real reason of the rejection.
But with the first track I’m sure it’s the arrangement. The rest sounds pretty good to me (maybe the distorted vocal could be less loud).
Cheers!
