Yah, the merger between Sirius and XM was a dramatic difference in programming content. XM had spent most of their time getting quality PM and on air talent, Sirius was basically a glorified Winamp playlist. As the channels merged, you found yourself going from a base of 5000 songs a channel to a few hundred. The folks who used to have XMPCR's (computer connected receivers) published a comparison of songs at one point but my google fu can't find it right now.
