Hurt by Johnny Cash. Amazing cover to the Nine Inch Nails original. It's just so...haunting and powerful.
Also, To Live is to Die by Metallica. Another powerful emotional song that has almost no lyrics whatsoever. It was written as a sort of heartfelt tribute to the late bassist Cliff Burton, and it really shows in their instrumentation and composition.
Would like to mention Space-Dye Vest by Dream Theater, just...another really good song in a sad way.
