Nothing like a pair of high-brow Europeans slapping each other in the streets, huh? In response to Nokia's forthcoming Comes with Music service, Sony Ericsson is confirming rumors by announcing a competing unlimited music download service dubbed Play Now Plus. The service, which will be available "solely through telecoms operators," will provide subscribers with access to millions of tunes, and customers can even keep up to 300 jams after their 6- to 18-month contract expires. According to SE's marketing head Lennard Hoornik, it'll be rockin' on Telenor within a few weeks, and it will spread from Sweden into more of Western Europe in Q1 2009 and into other world markets in Q2 2009. We're told that the service will run early adopters 99 Swedish crowns ($15) per month, and so far as we can tell, you don't have to have a specific SE phone to get in on the action.
