"The King of Rome" (sung by June Tabor, can't remember who wrote it) - about a racing pigeon. The last verse when the wee birdie finally makes it back to his roost is like a scene from a Ken Loach film.

When played well, the Irish set-dance tune "King of the Fairies" has me visualising little winged humanoids skipping across a woodland glade. I once saw Clan Na Gael dance to it, and they were almost as weightless as fairies.

Finally, countless Stan Rogers songs. You can smell the flowers of Bermuda, feel the ice cracking in the North West Passage, see the broken man on the Halifax pier... they are so vivid, I love them all.
