Spotify is reportedly obtaining a credit facility, a precursor to going public. This IPO could give Pandora shares a lift, but more importantly, Spotify will become a competitor to Pandora. Apple Apple should benefit in extending iTunes to Android. Android’s market share is vastly larger than that of Apple, so this move would give iTunes more exposure.

Installing iTunes would be redundant. On the PC, iTunes could receive a boost, since there are not as many successful music services on the desktop.
