They can on Dish's DVR's now.
besides, it's a paid service. If i paid $12.95/month for radio rights, and say, $5.95 for DAR (Digital Audio recorder) functionality, you're damn right I would say i contractually purchased rights to record whatever song i damn well please.
Sirius or XM would give a portion of the monthly fee to the label as a license fee.
Also, Sirius has many other entertainment channels I wouldn't mind recording and listening to later. i just don't have the time to sit for 2 hours to listen to Prarie Home Companion on saturdays, but sundays I do.. see?
Maybe a Boom box with timer capability.. since the rcvrs are so small.
