Always and interesting discussion. Here are a few more:
Tame Impala’s “Feels Like We Only Go Backwards” sounds like Pablo Ruiz’s “Oceano.” (Accusations made. No legal action that I know of.)

Radiohead’s “Creep” sounds like The Hollies’ “All I Need is the Air that I Breathe.” (Settled out of court with the latter’s co-writers Hammond and Hazelwood).

The intro to Air’s instrumental “Highschool Lover” sounds like Pink Floyd’s “Great Gig in the Sky.” (No action that I know of).
