Four of the biggest independent labels have renewed their agreements with music download service eMusic.

The labels are Beggars Group, which includes 4AD, Matador, and Rough Trade; XL Recordings; ATO Records; and Concord Music Group, which includes the jazz catalogs of Fantasy and Prestige. Artists across the four labels include the White Stripes, Dizzee Rascal, Paul McCartney, Joni Mitchell and Gomez.

After its launch in the U.S., eMusic expanded its subscription service into the U.K. and recently-announced sales of more than 150 million downloads worldwide.

The company says its overall label roster has reached 20,000, with a catalog of more than 2.8 million DRM-free tracks that will work on iPods as well as other devices. It has also secured new agreements with labels and distributors including Peacefrog, Echo, Blanco Y Negro Music and Pinnacle Entertainment.

"The catalogs of Beggars, XL, Concord and ATO are among the richest on eMusic, and we have enjoyed working with them to increase sales of both their best new releases and undiscovered catalogue," said David Pakman, eMusic president and CEO in a statement.

"We look forward to continuing our relationship with them, and to building our relationship with our new labels and distributors. We're sure eMusic subscribers will enjoy exploring all the great music they have to offer."

Simon Wheeler, director of Digital, Beggars Group said in a statement, "eMusic has been a key digital partner for Beggars for many years. eMusic subscribers' huge appetite for new music is perfectly aligned with our roster of creative labels and groundbreaking artists. With over 300,000 subscribers, eMusic is proving that the vast range and variety of independent music can deliver a compelling and satisfying music experience."
