UK digital music firm, 7digital has beaten Apple and Amazon in a key moment for digital music in Europe - it's offering music free of DRM from all four major labels.

The company this morning announced a deal with Sony BMG to offer music from that label DRM-free in MP3 format, meaning 7digital's four million strong song catalogue is all now available DRM-free.

It's a highly significant move, and means 7digital is the first digital music store in Europe to offer downloads from all four major labels, Sony BMG, Universal Music, Warner Music and EMI Records.

Tracks are sold free of DRM rights restriction as high-quality (320kbps) MP3 files - better quality than offered by iTunes Plus.

Taking the battle to the US, 7digital has also announced plans to launch in the US and Canada this year, the service is already available in the UK, Ireland, Germany, France, Spain, Italy, Austria and Portugal.
