8. Peace in the Valley (1969) • Johnny Cash (or Loretta Lynn or Dolly Parton)
Peace in the Valley was written in 1937 for Mahalia Jackson and this gospel classic has been recorded by numerous artists since.

9. Peace of Mind (1968) • Nina Simone
The refrain, All we need is peace of mind, should be everyone’s mantra. With all of the controversy surrounding Zoe Saldana’s protrayal of Ms. Simone in the not-yet-released biopic Nina, we’re betting she’s got this tune on replay.

10. Peace Go With You Brother (Wa-Alaikum-Salaam) (1974) • Gil Scott-Heron
Known more for his spoken word than his music, Peace Go With You Brother is a piece of music that haunts us as much as Scott-Heron’s passionate poetry.
