Task: Question Answering
Input (English): Passage: May 3, 2006, was the premiere of Dylan's radio presenting career, hosting a weekly radio program, Theme Time Radio Hour, for XM Satellite Radio, with song selections revolving around a chosen theme. Dylan played classic and obscure records from the 1930s to the present day, including contemporary artists as diverse as Blur, Prince, L.L. Cool J and the Streets. The show was praised by fans and critics as "great radio," as Dylan told stories and made eclectic references with his sardonic humor, while achieving a thematic beauty with his musical choices. In April 2009, Dylan broadcast the 100th show in his radio series; the theme was "Goodbye" and the final record played was Woody Guthrie's "So Long, It's Been Good to Know Yuh". This led to speculation that Dylan's radio excursion had ended.
On August 29, 2006, Dylan released his Modern Times album. Despite some coarsening of Dylan's voice (a critic for The Guardian characterised his singing on the album as "a catarrhal death rattle") most reviewers praised the album, and many described it as the final installment of a successful trilogy, embracing Time Out of Mind and "Love and Theft". Modern Times entered the U.S. charts at number one, making it Dylan's first album to reach that position since 1976's Desire. The New York Times published an article exploring similarities between some of Dylan's lyrics in Modern Times and the work of the Civil War poet Henry Timrod.Nominated for three Grammy Awards, Modern Times won Best Contemporary Folk/Americana Album and Bob Dylan also won Best Solo Rock Vocal Performance for "Someday Baby". Modern Times was named Album of the Year, 2006, by Rolling Stone magazine, and by Uncut in the UK. On the same day that Modern Times was released the iTunes Music Store released Bob Dylan: The Collection, a digital box set containing all of his albums (773 tracks in total), along with 42 rare and unreleased tracks.In August 2007, the award-winning film biography of Dylan I'm Not There, written and directed by Todd Haynes, was released—bearing the tagline "inspired by the music and many lives of Bob Dylan". The movie used six different actors to represent different aspects of Dylan's life: Christian Bale, Cate Blanchett, Marcus Carl Franklin, Richard Gere, Heath Ledger and Ben Whishaw. Dylan's previously unreleased 1967 recording from which the film takes its name was released for the first time on the film's original soundtrack; all other tracks are covers of Dylan songs, specially recorded for the movie by a diverse range of artists, including Sonic Youth, Eddie Vedder, Mason Jennings, Stephen Malkmus, Jeff Tweedy, Karen O, Willie Nelson, Cat Power, Richie Havens, and Tom Verlaine.
