The album deals with romantic love and relationships.
Despite radio-friendly singles and relentless touring by the band, the album was viewed by many as under-promoted by the label and a commercial disappointment compared to the success of their first album.
"Our Lives" was a minor hit, but the album was not as successful as their debut album Camino Palmero with sales totaling two million worldwide. Johnny Loftus at AllMusic, who gave it one and half out of five stars, said the album is "never adding enough of anything to be memorable or personal," and, that it is "the alternative to having an opinion."
Two didn't do as well in the charts as their debut album, as it only peaked at #54 on Billboard 200. In UK it peaked higher than their first album as it reached #9. World sales of the album reach 1,500,000.
