Well, yes.this is just the sacred cows thread pt. 2 now
Somewhat on topic, I think 'funkiness' is a great trigger for this. If you're in the mood for a shimmy or the atmosphere's right then you can love music that's got a nice bounce to it even if it's not actually that interesting in other respects - and in a different mood you just find it workmanlike and bland.
And yeah, I guess spaced-out depth (cf Basic Channel etc) is another one.
