Ok ignoring the fact that this isn't a speaker, if it was and the question is what would I play on a speaker this size, then probably this.

Sleep now in the fire

Caramelldansen

Goldeneye Surface level PTSD. Enemies beyond your sight horizon due to fog/snow, no map overlay for relative positioning, memorization was the only way to not get lost.

I could think of a few Ministry tracks, but I'll go with N.W.O.

Id freak out about having to make a choice and then just blurt out souvlaki space station because it seems like a safe bet of sm i like at high volumes.

"Turn Down for What"!

Thanks for the wiki link, OP. You sent me down a pleasing rabbit hole reading about the large radiotelescopes built by the USSR.
