Robyn performing "Cobrastyle" on the Late Show with David Letterman on May 1, 2008.
A little "Cobrastyle" history:
"Cobrastyle" began its life as "Press Trigger", a 2001 single recorded by Cobra over the Black Shadow label's Buzz rhythm (most people will recognize this rhythm from Sean Paul's worldwide hit "Give Me the Light").
In 2004, Teddybears STHLM recorded a new version of the song for their album "Fresh!", with guest vocals by Cobra himself - or Mad Cobra as he's generally known outside Jamaica. The Teddybears added a new chorus ("My style is the bomb ..."), inspired by the Sugarhill Gang's 1979 hit "Rapper's Delight", and called their track "Cobrastyle".
Robyn originally recorded this song for the soundtrack of the 2006 Swedish movie "Säg att du älskar mig". At this point, Teddybears member Klas Åhlund had already produced much of Robyn's eponymous 2005 album, and this track - now called "Girliestyle" - was actually credited to Teddybears STHLM vs. Robyn. "Girliestyle" featured reworked lyrics to fit Robyn better, removing much of Cobra's original Patois.
Later that year, Robyn released her "Rakamonie EP" in the UK, and one of the tracks included was "Girliestyle" - or "Cobrastyle" as it was now called. Since then, "Cobrastyle" has been included on all subsequent releases of the "Rakamonie EP" and her self-titled album (the latter was finally released in the US on April 29, 2008 - almost three years to the day after its Swedish release).
