Napster ( NAPS) rose 9% early Friday after the digital music service signed a deal to be the exclusive music subscription provider integrated into AOL Music.

The news comes as the Time Warner ( TWX) unit phases out its AOL Music Now service. Some 350,000 Music Now customers are being notified that their music accounts will be migrated to Napster unless they opt out, Napster said.

AOL and Napster expect to complete the service migration within the next 60 days.
