We went to some sort of party at someones home. It felt like an early 00's rural European house, maybe a farm house. With clay colored floor tiles and natural wood colored furniture and kitchen cabinets. The music wasn't so good and everybody knew, but the party was fun. The host and some people said, they can't change the music, because there is only this one CD and there is no other source. I had an mp3 player with lots of music in my pocket and mentioned it. The host pointed to his weird stereo that looked like a round tower fan, about 1m high, and said, we could play it if I get it hooked up.
We looked at its back side, but it was super complicated. It somehow took an hour to just get a cable attached. Someone got us three chairs. Now we were figuring out how to change the sound input from the only CD to the aux cable. Someone found a manual and we followed the complicated instructions entering weird button sequences choosing menu entries from it's fixed colored LED display.
Finally, when we had it set up, it was already the next morning, the party was over and an elder lady was sitting in one of the chairs with her morning tea.
We helped clean up a bit. Put the chairs and some blankets away and the dream ended.
