I thought 'Blurred Lines' was the song of the summer...this may usurp that honor.
If you don't know Bonnie McKee, you DO know her songs. She wrote/co-wrote: Katy Perry's "Part of Me," "Teenage Dream," "Last Friday Night" and "California Girls"; Ke$ha's "C'mon"; most of Britney's "Femme Fatale" album; Taio Cruz' "Dynamite"; Rita Ora's "How We Do."
So yeah, she's got a track record of success...and apparently a contact list that contains Macklemore AND Kathy Griffin...and KISS?
Oh yeah, grab a free download of the song at Bonnie's website
