I know there's a sticky for favorite software, but I found a fantastic application and I don't think people check the sticky very often. Pulsar for mac. It's a great app for streaming sirius or xm on your mac. You don't even need to pay the extra fee for all the channels or CD quality. http://www.rogueamoeba.com/pulsar/ It's 15 bucks for the unlocked version. The demo adds noise to the sound after 20 minutes.
