Note: "California Gurls" and "Dark Horse" were Katy's only non-solo #1s on the Dance Club chart, as Kanye West did not feature on the dance remixes of "E.T." (remix producers remixed the solo album version instead). This means 14 of Katy's 16 Dance Club #1 hits are solo.
She'd have a #1 for every year, if only she'd pushed one more single from PRISM in 2015 / sent EDIAH to clubs.
Imagine if "By The Grace Of God" topped the Dance Club chart, a "Til It Happens To You" tea.
But YAS legend.
