There are, at least, two acts known by this name.
1: a pseudonym for Richard X
2: a indie-pop band from the dutch village Joure who are not signed but have a significant fan base in the north of the Netherlands. the rest of this article will be about the first mentioned Girls on Top.

1: Girls On Top was the pseudonym used by record producer Richard X between 2001 and 2002. As part of the bootleg music craze of the time, Girls On Top had a string of limited edition underground singles released on vinyl only. Richard X used the method of taking the instrumental music track of one pop record and the accapella version of another pop record and splicing the two together.

The most successful record produced by Girls On Top is "We Don't Give A Damn About Our Friends" which became the comeback single for the Sugababes in 2002. The 2001 track "I Wanna Dance With Numbers" made some sucess on dancefloors around the globe mashing up Whitney Houston's vintage masterpiece "I Wanna Dance With Somebody" with Kraftwerk's classic "Numbers".
