Spice Girls discography sold 23 million copies worldwide and was certified ten times platinum by the British Phonographic Industry (BPI) in the UK. The fourth Spice Girls single, the double A-side "Mama"/"Who Do You Think You Are", also went to number one in the UK. In November 1997 the group released their second album, "Spiceworld", which has been certified five times platinum by the BPI. The album produced three number-one singles in the UK, "Spice Up Your Life", "Too Much" and "Viva Forever", with "Stop" peaking at number two, ending the group's run of consecutive number-one singles in the UK. In May 1998
Don't Say You Love Me (M2M song) was M2M's biggest hit and is their most recognisable song. While their next single, "Mirror Mirror", was a top 40 single in Australia and Canada, and reached number 62 on the "Billboard" Hot 100, "Don't Say You Love Me" would remain M2M's only top-40 hit in the US, and their only hit at all in many other countries. The song has been called a one-hit wonder. While speaking favourably of the duo, in 2014 Abby Devora from MTV ranked M2M and the song at number 2 on her list "9 Girl Group One-Hit Wonders You Need To Remember Right Now".
