Harmonic minor
In the late '90s and early '00s, pop songs often used the leading tone in a minor key (i.e., the note one half-step below the tonic), along with the V7/vi dominant chord to which it belongs.
Ancestors
There is [...] a tradition of pure [i.e., "harmonic"] minor modality, blues aside, in the R&B music of Stevie Wonder and Michael Jackson; this is the heritage of the Backstreet Boys.
— Walter Everett, "Pitch Down the Middle", from Expression in Pop-Rock Music (2008), p. 172

Eminem
Despite Eminem's outspoken disdain for the boy bands of the '90s, many of his early songs inherited the harmonic minor scale from those very bands.
