"When Love Takes Over" is a synthpop[REF] and "uplifting floor-filler"[REF] produced by Guetta and his associate Frédéric Riesterer [REF].
After gaining Guetta's approval to write vocals for the song, Rowland took the instrumental version to London,[REF] where she wrote the bulk of the lyrics with The Nervo Twins (Miriam and Olivia Nervo) before sending the song back to Guetta,[REF] who added his own contributions with Frédéric Riesterer.
