Billboard Hot 100: #91(new) Birthday
Dark Horse still rulling at #3
such a great debut with the only promo being the lyric video =)
the single was officially released today (April 16) and will be sent by Capitol to mainstream and rhythmic radios on April 21, so it will increase a lot during the next two weeks
Katy did right when she picked Birthday instead of Legendary Lovers, the second deserves a great moment to be released like between her PRISMATIC Tour USA dates during the summer
