With love in the air — whatever that means — I took the popular “eff, marry, kill” game and applied it to stocks. If I took a look at three related companies, which one would I want to date for a short-term trade? Which one would I like to marry as a long-term investment? Which one would then leave me with no choice but to rub out and possibly short?

On Monday I gave it my first crack by taking a look at companies that are revolutionizing the way we listen to music. I went with Sirius (Nasdaq: SIRI), XM Satellite Radio (Nasdaq: XMSR), and Apple (Nasdaq: AAPL). My answers are already in the headline, but you would be best to read the entire article to find out why I came to those conclusions.

I take a closer look at how Google (Nasdaq: GOOG) is teaming up with Digital Music(Nasdaq: DMGI) to offer up Digital’s more than 4,000 hours of video content through Google’s YouTube site for free. Digital will get a piece of the ad revenue action. Still, do folks really want to see My Favorite Martian or Gumby on YouTube when some embarrassing pratfall caught on a camera-phone is just a click away?
