I give a death metal boy band about as much a shot as making it as TiVo's (NASDAQ:TIVO) new music service through RealNetworks' (NASDAQ:RNWK) Rhapsody.

Really.

Sure, the new offering looks great on paper. Many of TiVo's 4.2 million current subscribers already have their set-top boxes glued to the Web for programming updates. Why not charge them $12.99 a month to deliver unlimited streaming of Rhapsody's growing library of more than two millions songs?

I'll tell you why not. They're already paying as much as $16.95 a month for a TiVo subscription. Do customers really want to spend another $13 for music? Especially when they're going with TiVo over a rival's free DVR service because they're fanatical about consuming video content, not music?

Besides, I can listen to music for free through my TiVo. Whether it's going through Live365.com for Internet radio or playing stuff off my PC after a TiVo desktop software upgrade, is Rhapsody all that compelling?

Yes, it's a great feature for existing Rhapsody subscribers. Now they'll have one more way to milk more out of their existing subscriptions. I just don't think there's a whole lot of overlap between the services, even if they both represent paid subscriptions for something in which inferior alternatives are plentiful yet free.

I don't blame either company for trying. RealNetworks needs deals like these to offset Napster's (NASDAQ:NAPS) growth spurts. TiVo never seems to say "no" to a potential partner. I just see bigger potential in more logical pairings -- like TiVo offering Amazon.com (NASDAQ:AMZN) digital downloads directly into its hard drive -- than a music deal that will sadly fall on deaf ears.
