I have XM in my car. The have a free online listening interface included with the subscription. I'm listening to it now as I type this at the office. It just streams XM via my Windows media player. Very nice.
So, the question is, has anyone figured out a way to stream XM on the droid? There must be a way since it's just a web based radio, effectively.
I haven't played with Pandora much but my son has used it for years and loves it. I just have a few XM channels I really like and would love to have them on my phone.
