My goodness this is difficult, assuming it is intended to be the only music I’d be able to listen to forever. If i thought about it over several weeks I might have some differences, but if I had to grab them now this is what I’d choose:
Beethoven/Bruch - Violin concertos
Deep Purple - Made in Japan
Genesis - Lamb lies down on Broadway
Led Zeppelin - LZ1
Pink Floyd - Dark side of the moon
Puccini - Turandot
Roger Waters - Amused to death
Twelfth Night - Live and let live
The Who - Tommy
There would need to be electricity, and a good hifi system, digital of course - though extensive treatment likely to be necessary against the humid atmosphere, especially the speakers. With no neighbours outside playing would be possible allowing fantastic sound through elimination of room effects …almost, as sufficient protection from rain also needed.
If no electricity then a wind up gramophone needed, and picking from available 78s - when I’d end up with only classical + opera.
Mind you, with a digital system I’d get a memory stick and copy my entire collection on it, and sneak it in my pocket!
