As Loudon Wainwright III says in his song "In C," he likes to sing about "my favorite protagonist — me."

The callow croon over a pulsating beat, the massed harmonies in the chorus, the lyrics about partying that name-check Katy Perry and include a wistful wish for a nameless girl to kiss the singer — this is boy-band music at its newest and its most timeless. The five young guys who comprise One Direction are single-minded.

Dierks Bentley has a nice, deep voice; an open, friendly demeanor; and a knack for working in a variety of country-music genres, from bluegrass to power ballads. For all that, it's always been difficult to pin down what Bentley aims to do. Although he's only in his 30s, Bentley sounds as though he's working through a bit of a midlife crisis on his new album Home. Take, for example, the single "Am I the Only One," a novelty tune about going out to party with a twist — not many of Bentley's pals want to join him, because they've settled into adulthood, and he hasn't.

The song "I Got You Babe," on Bahamas' new album, Barchords, is obviously not Sonny and Cher's "I Got You Babe." This version is an original song the Canadian singer-songwriter Afie Jurvanen, who records under the stage name Bahamas, has written about holding and losing someone.
