Canadian wireless operator MTS Allstream is launching a full-song music download service with technology provider Groove Mobile, the same company behind the Sprint Music Store.

The Allstream service includes the IODA Free Track Chart, which offers four to five free tracks from the IODA catalog, refreshed every week, as a way of promoting new artists from the independent music distributor.

About 300,000 Allstream subscribers will have access to the service at launch. It is the sixth wireless operator in North America using the Groove Mobile music download service.
