The metal legends returned in 2013 with their critically acclaimed album, 13, and today we'll see what you think of 'Loner', the new single from the disc.

With a main riff that unmistakably came from the brilliant mind of guitarist Tony Iommi, 'Loner' has my vote for best song on the album. While I'm a huge Ozzy fan but Black Sabbath begins and ends with Tony Iommi for me. That being said, the dynamic between Ozzy, Iommi and Geezer Butler is hard to deny. Sabbath have made a lot of cool records over the years but there's nothing like hearing Ozzy's voice over those dark, driving riffs.

Give 'Loner' a listen and weigh in on the tune below.
