Where to start with what's wrong about all this?
Firstly, the "80s" showed that a cultural theme doesn't work when you do not define it very clearly.
The 80s did not exist, and when a team did something slightly more different (Lopareva/Brissaud) it was already unrecognizable for many in how far it was 80s. So we got almost only Anglo-American top charts of the 80s, apart from the Russian domestic scene, where the choices were a bit different. I saw this tweet from Weaver now, talking about women's agency or what not as what the 80s were about - well, maybe for you. Like I said my first thought was Tchernobyl. So, when the music is supposed to be recognized by the majority of a worldwide or at least northern hemisphere audience /judging panel, you will get no diversity at all in a topic which, by its words, should not only be about a very limited kind of pop culture.
Also, women's agency is not a sportive category. At all. Also, ice dance/skating per se is not really the place for social movements and such. It's often a cringe festival, and so we hardly got any programs that addressed anything, but, of course, Top Gun etc. with the macho man.
Dance party 20th century is not a theme. It is so open you could just stop having themes at all. I think the goal of this, if it's all true, is having upbeat more current music for the next, Olympic year - and this one is just the rehearsal year.
If you want upbeat current music to gain a certain audience, name a range for beats, name "c and d major" or something, say "songs mustn't be older than 2020" or such and that's it. At least those are clear categories where you know whether you fit the criteria, even if you choose songs that nobody in the US has ever heard of. Dance party is nothing, there is no definition for that term other that you have to dance, which of course you have to do in ice dance.
Of course there are some steps and technical restrictions outlined but I'm not sure how all of that is connected and what Paso doble has to do with the dance party and if that's even Paso doble...

I did find an RTL (German trash tv) playlist though for Let's Dance for Paso doble and it includes the Pirates of the Carribean, The Mask of Zorro and Malaguena. Well, you can play what you want at your dance party, right?

I'm just waiting for the André Rieu "dance parties".
