It looks like Nokia-rival Sony Ericsson is going to battle it out with the Finnish company in the realm of the music download scene. While Nokia may have struck the first blow with their Comes with Music service, Sony Ericsson has been reported to be considering going the same route.

If Nokia has chosen to bundle their servic with their Nokia 5310 XpressMusic phone, word is that Sony Ericsson is planning to offer theirs with their Walkman series of phones. No word though if it’ll be available for the entire line or specific models only, but we’ll probably hear an official announcement within the month. If everything goes accordingly, it might be offered in Europe before the year ends. The rest of the world will probably have to wait until next year for the service to roll out in their region.

As for the here and now, Sony Ericsson currently has an existing mobile download service with around 5 million DRM-free songs at their disposal. With that massive collection at their beck and call, Nokia might be in for some stiff competition as far as the music download scene is concerned.
