London: Swedish singer Robyn says she enjoyed working on rapper Snoop Dogg's single "Sensual Seduction" even though it was a "sterile collaboration" since they didn't even meet for the recording.

Robyn said: "I was asked if I wanted to put vocals on his new single and of course that's something you can't turn down.

"I've been listening to him since I was a little kid. I think he's the coolest guy out there, probably the only rapper that's still alive that I really like," she added.

Robyn and Dogg didn't even meet and the vocals were added in a Stockholm studio after the sound files were sent to her, reports ananova.com.

She said: "My collaboration with Snoop was really sterile but I just loved to get that chance to do something on that song."
