Mamma Mia

"Mamma Mia" by ABBA is a popular song in the original key of A major. The song was released in 1975 and quickly became a global hit, reaching the top of the charts in several countries. It was written by Benny Andersson and Björn Ulvaeus, two members of the Swedish pop group ABBA. The song is about a woman reflecting on a past relationship and expressing her regret for letting love slip away.
