Hey David,
This is AWESOME! I love horn songs.. I used to play in a Chicago/BST cover band in the 70s, and I still have a special place in my heart for music like this. I'd like to hear more about how you created the horn tracks. They sound very realistic to me. I'd like to make some horn songs but Coyote MIDI player ain't the way to roll for that task.
If "listenability" is a desirable trait for a song to have, for me this is one of those songs where I want to listen again as soon as it ends. VERY "listenable"
You mention the drums as being "busy", but to me I hear stylistic choice, and its a choice that works in that songs. Stylistic choices are what keep songs from sounding like every other song, so.. winning!
Two enthusiastic thumbs up from me, my friend!
