About Do I

"Do I" is a song co-written and recorded by American country music artist Luke Bryan. It was released in May 2009 as the lead-off single from his album Doin' My Thing. Bryan co-wrote the song with Dave Haywood and Charles Kelley of the group Lady Antebellum, whose co-lead singer Hillary Scott is featured on background vocals. "Do I" is about a couple questioning the status of their relationship. The song received mixed reviews from critics wary of Bryan's delivery in the lyrics. "Do I" peaked at number 2 on both the Billboard Country Airplay and Hot Country Songs charts respectively, both times behind Lady A's own song "Need You Now". It also gave Bryan his first top 40 hit on the Hot 100 chart, charting at number 34.

The song was certified 2x Platinum by the Recording Industry Association of America, and has sold 1,633,000 copies in that country as of November 2015. The song also charted in Canada, peaking at number 66 on the Canadian Hot 100 chart. An accompanying music video for the song, directed by Shaun Silva, is set in a high rise condominium where Bryan contemplates his relationship with his girlfriend.
