For music, something about the corporate library music of my childhood lifts my spirits with its bombastic naffness. I've recently discovered fusion, which I see as the precursor to that. A guy called Terminal Passage collects old 70s vinyl and digitises them for Youtube.

I particularly recommend Neil Ardley's Kaleidoscope of Rainbows: https://www.youtube.com/watch?v=MgdfA4YJWP0 (especially Rainbow Seven/Epilogue)
