To celebrate the old 45RPM vinyl single, Apple's iTunes has launched a new promotion that duplicates the a-side and b-side format in a digital style.

Apple explains; "The vinyl 45 RPM record once ruled jukeboxes and helped bring artists into the hands of true music fans".

"It was smaller and cheaper than a full-length, featuring two top-notch tunes for a great price".

"iTunes is bringing this concept into a new age with D45s - two great tracks at an equally great price".

Made possible in part to iTunes' move towards variable pricing, in the States pricing is from $1.49, while here in the UK the D45 downloads cost around £1.19.
