Universal Music, the world's largest record label, has agreed to buy Dreamworks Records.
Nelly Furtado is one of Dreamworks' artists
The Dreamworks label includes artists such as pop singer Nelly Furtado and the band Papa Roach.
The music business is currently going through major changes as it struggles to counter falling sales and the impact of unofficial online music sales.
Last week, Sony Music - the second-largest music company - said it was planning to merge with Bertelsmann.
EMI and Warner Music have also been in talks about a possible merger.
Neither Universal nor Dreamworks disclosed the value of the deal, although the Reuters news agency reported a person close to the talks as saying it was worth about $100m (£60m).
Dreamworks Records is the music unit of the Dreamworks entertainment company which was formed in 1994 by film and music leaders Steven Spielberg, Jeffrey Katzenberg and David Geffen.

"(The Dreamworks team) have built an incredible roster comprised of gold, platinum and multiplatinum-selling artists as well as a host of new acts who will be successful in the future."
Mo Ostin, principal executive at DreamWorks Records, said: "Despite the challenges of the music business today, Universal is acquiring a wonderful asset and the sale will assure the strongest possible future for our artists."
