The Mars Rover engineering team plays a tune or two each morning for Spirit and Opportunity. The songs played are usually related to the day's events. The Beatles "Good Morning, Good Morning" for the first morning, Ratt's "Round and Round" when the rover is turning, etc.
I was perusing this site which lists every song played for the Mars Rover. Some of the tunes are good, some are really bad. Below are my favourite five songs from the Mars Rover Soundtrack.
- Otis Redding - Sittin' on the Dock of the Bay
- Louis Armstrong - What a Wonderful World
- The Beatles - Here Comes the Sun
- The Pixies - Where Is My Mind?
- Nirvana - On A Plain
Below are my least favourite songs from the Mars Rover Soundtrack.
- Baja Men - Who Let the Dogs Out?
- Sade - Smooth Operator
- Sting - If You Love Somebody Set Them Free
- Diana Ross - I'm Coming Out
- Whitesnake - Here I Go Again
I recommend "When Did You Get Back From Mars?" from I Mother Earth upon their return to earth.
