Conviction is Aiden's third studio album which was released August 21, 2007. It is the first of their releases to carry a Parental Advisory sticker although it is not the first to contain profanity. Best Buy editions of the album contain the 2 exclusive bonus tracks "Here Lies the Waste" and "So Far Away". The album has been one of the band's most commercially successful albums to date. The first single from the album, "One Love", was released on their MySpace page on July 23, 2007.
The band finished recording after their brief UK arena tour supporting Lostprophets and returned to the UK again to play the Download Festival before doing a more complete tour in support of the album.
Every record that we've done, being the main songwriter for the band, has been a reflection of what's going on in my personal life. So yeah, Nightmare was pissed but by the time we did Conviction I'd achieved so many of the things that I've always dreamed of doing: walking out on the main stage of the Warped Tour, playing all summer long with NOFX, touring with HIM, played Download in front of 50,000 people. With Conviction I wasn't pissed. I wasn't angry and that came through in the music. I was a bit bummed that some Aiden fans turned away from it because I was a little bit more melodic or a little bit different from what they had been expecting from us but I don't sit down and think, 'If I write this it will sell bucketloads' because I wouldn't be able to sleep at night thinking that way.
