UK users now have access to Rdio, an online music streaming service which has previously been exclusive to the US.
Now that the service has made the jump across the pond, they’re offering new users six free months of streaming, with no credit card details required. However, you’re only able to listen to a certain amount of music each month under the free trial, but your monthly allowance is clearly indicated at the top.
I’ve been using Rdio for a couple of months through Media Hint, and while it hasn’t stolen me away from Spotify yet, it’s definitely an extremely good service. Definitely worth a go.
