12 songs you had no idea were written by Prince

Prince died a year ago Friday, and he is still truly missed. His songs made an indelible mark on pop music and the industry behind it.

While he was making albums of his own, Prince, a prolific songwriter and musician, also wrote and produced songs for other artists. And some of them turned into major hits. There are also quite a few covers of Prince songs that became hits for other artists, like Cyndi Lauper and Alicia Keys.

Prince often used a pen name in these collaborations with other artists to keep his own spotlight away from the songs.

Here are songs by other artists that were actually written by Prince:

"Manic Monday," The Bangles (1986)

Prince may have not worked a nine-to-five himself, but he sure understood what it was like. For this song, his pen name was just Christopher.

"Nothing Compares 2 U," Sinead O'Connor (1990)

"Stand Back," Stevie Nicks (1983)

Nicks cowrote this song with Prince, and credited his song "Little Red Corvette" as the inspiration for it.

"How Come You Don't Call Me Anymore," Alicia Keys (2001)

Prince's version of this song was on his hit album "1999."

"Love Song," Madonna feat. Prince (1989)

Prince cowrote this song from the album "Like a Prayer." He also contributed some vocals to the song.

"I Feel For You," Chaka Khan (1984)
