So, in general for me the most important songs of any music kit are in pretty much this order:
*MVP Anthem (it's the one track you get to showboat to the entire server, i mean, come on)
*Bomb 10 second warning (having muted most of the ingame music to better hear footsteps and such, this is the one music track that has actual gameplay use)
*Main Menu

I would love to enable the start round music as well (especially with some of the choices you made here), but for gameplay reasons, I only want to have very short tracks there that end before any contact can happen. And as I have various music kits on shuffle (which makes those stattrack numbers climb ever so slowly [yeah, yeah, not a major concern, but still, valve, pls fix]) I tend to just mute everything apart from the above three for playing comp.

That all having been said, some specific feedback:
While I like the bomb planted soundtrack, the ten second one feels pretty rushed. I like that you put some thought even in the midpoint for those who didn't forget their kits, but I'd like the tempo of the longer one.
Now, the songs by your dad have become super iconic for lots of us. Please consider the song you used for Start Round Action 3 as the MVP Anthem! For me, it is lots more iconic and hype than the one you decided to use and it is in my opinion the much better suited place to showcase it (btw, what IS the name of that one?). Also, how about Only the Lonely for the Main Menu as well? For those I feel they don't really fit that well into the start round slot but it would be a shame not to include them.
