|This recent Rdio update has bug fixes.|
I tried out Rdio for a while since it was a AppRadio compatible app. The interface is simple but had a few issues. Sometimes a few tabs would just not click. Rdio is a subscription-based music streaming service and gives the user the ability to download tracks to their device for offline use. A basic subscription costs $9.99 a month. I must mention that I don't have an active subscription anymore.
