Harkening back to the days of the vinyl 45 rpm record, the iTunes Store has launched a new section of the store for “D45s.” As with vinyl 45s, these new digital packs contain two songs, traditionally made up of a single and B-side. Currently available D45s include selections from artists such as David Bowie, Prince, Coldplay, Foreinger, and The Doors; pricing ranges from $1.49 to $1.99.
