These are the 7 songs musician Carlos Santana wants to hear in every elevator and mall

Musicians MC Hammer and Carlos Santana both had two minutes to speak openly to a room full of politicians at the U.S. Conference of Mayors' annual meeting in San Francisco on Friday.

MC Hammer started with a rap. Santana opted to list songs that he thinks will change society, if they are listened to in malls and elevators everywhere.

"There are seven songs that I believe have the power to change the mindset of subconscious human," Santana told the mayors. "If these songs were played in shopping malls, elevators, and other places, I believe you would notice a visceral change in human behavior and conduct." 

Take a listen to Santana's seven:

1. "What a wonderful world" - Louis Armstrong

2. "What's Going On" - Marvin Gaye

 3. "Imagine" - John Lennon

  4. "One Love" by Bob Marley

 5. "Blowing in the Wind" - Bob Dylan

 6. "A change is gonna come" - Sam Cooke

 7. "A love supreme" - Originally by John Coltrane, played here by Santana himself
