Skoda launched a website called The Family Composer, which asks users to enter their Facebook and Spotify information (which means it won't work for U.S. residents -- until later this week, most likely) to find a lady or gent who marches to the very same drummer. After being matched, a user can message his/her future mate and ask him/her to jointly test one of Skoda's family vehicles.
The idea is interesting -- if a little half-baked. After all, what does having the same taste in music have to do with buying a car? (Aside from avoiding a lifetime of misery in said car if your mate likes, say, recordings of Tibetan singing bowls while you prefer death metal.) Perhaps if there was some tie-in with Spotify, it would make more sense: Give free Spotify service to successful matches.
If you're looking for similar matchmaking service, without the brand tie-in, you can check out Tastebuds.fm, a dating site that matches users based on musical tastes.
