"iRadio is coming. There's no doubt about it," a music industry source tells The Verge's Greg Sandoval. After months of tough negotiations with studios, Apple (AAPL) is said to be aiming for a summer launch. The company's reported plan to limit the service to Apple hardware stands to affect its popularity with customers who listen to music on both Apple and non-Apple gear. Sandoval adds the music industry has "a love-hate relationship" with Pandora (P), believing (in spite of Pandora's gripes about royalty rates) it "chokes off demand" for more profitable services.
