"9 PM (Till I Come)" is a song by German electronic dance music producer ATB, featuring uncredited vocals by Yolanda Rivera released as his debut single and the lead single from his debut album Movin' Melodies (1999).

"9 PM (Till I Come)" was the first song to feature the sound of a pitched guitar, which was so striking for the first singles to be released as ATB. Apparently Tanneberger was fooling around with his studio-equipment, while he was showing someone around. He liked the sound so much that it became his trademark, and a worldwide dance hit.

"9 PM (Till I Come)" peaked at number 14 on the German Singles Chart. Internationally, the song was also successful. The single entered at number one in the United Kingdom for the week ending July 3, 1999 and stayed there for two weeks, becoming the country's fifth best-selling single of 1999. As of July 2014, it has sold over 890,000 copies in the UK. The song was also number one in the Republic of Ireland for 4 consecutive weeks. It was number three in Belgium and Norway, number five in Belgium, number seven in Italy and number ten in Australia.

"9 PM (Till I Come)" became so popular that in 2000, Electronic Arts decided to use it in their game, FIFA Premier League All Stars 1999, as their title song. The version which was used was the Signum remix. However the Sequential One 1999 remix is a version that has been very popular in clubs throughout from 1999 onwards and was used for the UK radio edit of the song.
