Unlike the Amy Winehouse song
of the same name, this is a metaphorical song. Rehab means we have to get over the guy. So we talk about checking ourselves into rehab, and we compare the guy to a disease or an addiction. (thanks, Amber - mocksville, NC)
This was written by Justin Timberlake, Timbaland and Hannon Lane. Timbaland also produced the song and contributed backing vocals with Timberlake on the tune's bridge.
Rihanna told Entertainment Weekly about Timberlake's contribution to this song: "Well, Timbaland was on tour with Justin and we had to follow Timbaland, really. So we went to Chicago first and one night after the show, Justin just came into the studio and he started messing around, making a beat. And it was fun. We played around with that one, too. And when we came to New York, Justin came back to the studio and he was like, 'I wanna write this song for Rihanna.' So Timbaland had an idea and he knew he wanted to call the song 'Rehab' and he had a beat. So then Justin Timberlake came in and he just put his thing on it. He wrote the song in his head. He didn't write anything on paper. He went into the booth and sang it and I was very, very impressed. We all loved it."
This was Rihanna's eighth single to be taken from her album Good Girl Gone Bad.
This song's arrival on the Billboard Hot 100 in November 2008 meant that all eight releases from Rihanna's Good Girl Gone Bad album had become hits. It was the first time an artist had extracted eight Hot 100 hits from one album since Shania Twain achieved an octet of chart entries from Come On Over between 1997 and 1999.
