Say something...

So there are really four things about songs that make me like them. First, I like songs that affect me emotionally; second, I like songs that interest me musically; third, I like songs that I can sing and enjoy singing; and fourth, I like songs that I can relate to. Most songs only hit one or two of them, occasionally three. A very, very few hit all four.

The real wildcard there is the second one; "interesting me musically" is both unpredictable and a moving target... But is also the biggest factor.

It came to mind, because "Say Something" (by Great Big World and Christina Aguilera) managed to hit all four, and is currently up there with "Love is Love" and "The Moon Song" as one of my couple favourite songs. I'm enjoying it. You should go listen to it if you aren't familiar.
