Another player enters the cloud music space

The sky is getting pretty crowded these days.

The already competitive cloud music space has another competitor stepping into the fray. Best Buy today unveiled plans for its own service, letting people access their digital music collection from virtually anywhere.

Dubbed Cloud Music, the service will compete with Apple's iCloud, Amazon's Cloud Drive and Google Music – three tough competitors whose reach in the digital space is much more dominant than the brick and mortar retailer.

It's a curious offering. The free service will only allow you to access music via the Best Buy Web player. If you want to add an app to access tunes on your iPhone, Android device or Blackberry, it will cost $4 per month. (Amazon and Google's services have a more robust free option.)

The company's also not offering an easy transfer service for music you buy in the store. Users will have to digitize and upload their songs and playlists on their own – a requirement that could steer people to other offerings.
