• This was originally released in Robyn's native country Sweden in 2005, reaching #18. It was credited solely to producers Kleerup with Robyn relegated to guest star status. The following year import copies began to be played in British clubs and it was re-released in 2007, this time as a Robyn single, with Kleerup reduced to the "featuring" role.
• Robyn is a Swedish Electro Pop singer, who had two #7 hits on the Hot 100 in the mid 1990s with "Do You Know (What it Takes)" and "Show Me Love." The latter also peaked at #8 in the UK. She then disappeared until 2007 when she had a UK chart topper with this song.
• Robyn told the Metro newspaper October 25, 2007: "With Every Heartbeat is not a typical #1 song - it doesn't really have a chorus and it has a weird string break in the middle, so it wasn't expected. But when it started to climb up the charts, we all watched it very closely. The song deserved to be a #1, so I'm not surprised but it wasn't expected either."
