Step One is the debut album by British pop group Steps. It was released in the UK and Europe on 14 September 1998. The album charted at number two on the UK Albums Chart upon its release, going on to spend 64 weeks in the chart. It was beaten to number one by This Is My Truth Tell Me Yours by Manic Street Preachers, who also beat Steps' single "One for Sorrow" to number one on the UK Singles Chart with the song "If You Tolerate This Your Children Will Be Next". In February 2000, the album was re-released in the US, containing songs from both Step One and its successor, Steptacular. The tracks "5,6,7,8", "Last Thing on My Mind", "One for Sorrow", "Heartbeat" and "Better Best Forgotten" were released as the singles in UK. In 2000, the album was certified 5× Platinum by the British Phonographic Industry, and has sold over 1.4 million copies in the UK.

"One for Sorrow" is a song by British pop-dance group Steps, released as the third single from their debut album, Step One (1998). It also became the quintet's first single to reach the top five on the UK Singles Chart. Debuting at number two and spending 11 weeks on the UK chart, the song established Steps's intention to revive the ABBA sound, striking a considerable resemblance to their 1980 hit "The Winner Takes It All". A remixed version became their debut US single in 1999 and was featured on the Drive Me Crazy film soundtrack. It peaked at number 38 on the US Billboard Hot Dance Club Play chart in October 1999.
