LIST INCLUSIONS
All acts are listed alphabetically, solo artists by last name, groups by group name excluding "A", "An", and "The".
Each act's total of number-one hits is shown after their name.
Artists who hit number one prior to the start of the Hot 100 are included here; a song that topped multiple pre-Hot 100 charts is counted only once towards the artist's total.
All artists who are officially namechecked in song credits are listed here; this includes one-time pairings of otherwise solo artists and those appearing as "featured". Exceptions to this rule:
# Paul McCartney's hits with Wings are credited to "Wings" even though many of them were released as "Paul McCartney & Wings". McCartney's total is only from hits not attributed to Wings or the Beatles.
# Both Wham! and George Michael get one credit for "Careless Whisper". Technically the song is a solo recording and was released as such in many parts of the world except the U.S., where it charted as "Wham! featuring George Michael".
Artists associated with a group who reached number one, yet have their own solo page in Wikipedia , are not listed here unless they hit number one as a solo artist.
° symbol indicates that all or part of an artist's total includes number-ones occuring on any of the pre-Hot 100 chart(s) listed above (1 January 1955 through 28 July 1958).
