The song "Boots of Spanish Leather" by Bob Dylan is one of the greatest songs, and is acoustic itself. But I totally love the remake, which is more acoustic sounding to me by the group "Ida".

Now this song was always acoustic, not sure if your question only wanted acoustic versions of non acoustic songs. But one of my favorite songs of all time is "Going to California" by Led Zeppelin

Creep- Radiohead
