Norwegian Wood" is the one.

Norwegian Wood (This Bird Has Flown). That’s the track—1965’s Rubber Soul. George Harrison picked up the sitar on set of Help! and got obsessed after meeting Ravi Shankar. He used it on this song, and it became the first prominent sitar part in a Western pop song.

It’s not a long passage—just a few bars during the verses and the outro—but it changed everything. Suddenly every band wanted a sitar guy. Harrison went deeper later (see: “Within You Without You”), but Norwegian Wood is where the whole thing started.

Fun fact: Lennon wrote it about an affair, but the sitar makes it sound like a meditation on furniture.
