I love XM
Another example occurred last September with an event simply called "IT." The premise was that they played every single top-charting pop song ever made from the 1930's through the 1990's in chronological order. This event spanned all of their "Decades" channels and took a little more than 3 weeks. The great thing about it was that, while listening to a certain time period - let's say, June of 1977, for example - memories would flood back of what I was doing during that timeframe and listening to those tunes on the radio. It was exhilarating and magical, as well as enlightening. For example, listening to the segments during the mid-1980's, I remembered why I listened to a lot of alternative radio around that time; music was massively overproduced and boring as hell!
The diversity of music that you find on satellite radio is what really makes it worth the subscription price for me. If I get tired of listening to classic alternative rock, I can switch to gut-crunching metal, punk, hip-hop, funk, bluegrass, folk, country, blues, electronic, reggae, or even reggaeton. The channel that was the most pleasant surprise for me was channel 27 - Cinemagic. The premise seemed pretty stale to me at first - they only play sound clips and the soundtracks from movies. However, I have discovered wonderful films like Kinsey and Whale Rider that I wouldn't have even considered before just by listening to a clip of dialogue that normally wouldn't make it to a trailer. I have also found myself picturing scenes of movies that I love by listening to the soundtrack. For example, just this past Monday, my son and I were listening to a track from The Incredibles where we could picture the whole scene unfolding. We were laughing about how much we could peg each part of the scene to each movement of the soundtrack.
Everybody I work with asks me about why I would pay money to listen to the radio. I always explain to them that people used to say the same thing about cable or satellite television, and now people can't see why you wouldn't. I also warn them that the same thing holds true for satellite radio; that once you go satellite, there's no going back to regular radio, especially if you drive a lot.
