First it was Universal, then EMI expressed interest, and now Sony BMG has hopped aboard Nokia’s “Comes With Music” bandwagon. The basic idea is that certain Nokia devices will include unlimited music downloads for a year.

At the end of the year, you’ll apparently be able to keep everything you’ve downloaded and transfer it to your computer and new Nokia devices — songs will be DRM’d but won’t expire.

The feature launches in the second half of this year and will be available on a number of Nokia phones marked with the “Comes With Music” logo.
