Since you mentioned Coldplay I remember them getting sued for stealing the melody from this song and using it in Viva La Vida. If you listen you'll get it - about 50 seconds into it you could probably sing along with the guitar if you wanted to - "I used to ruuuuule the world...." As annoying as it is to hear an artist stealing from someone else's work, this one did allow me to find a really great song out of it. Here's If I Could Fly:

& I think the Vanilla Ice one was really obvious - I kind of assumed that everyone recognized Under Pressure from it anyways as them sampling the song in Ice Ice Baby. Lol. I enjoy both though.
