The companies did not disclose the terms of the deal.
We7's chief executive Steve Purdham reportedly said the partnership would help the music service earn revenues through advertising, which would be used to pay artists and music companies whose tracks are played on the website.
The music service currently has three million monthly users. The majority of these use the service for free, and listen to audio advertisements in between songs and watch display advertisements across the site.
Last month, We7 launched a subscription service which allows users to turn off advertising for either £4.99 or £9.99 per month.
