He looks fine to me. It's not bad, but I wouldn't listen to it at home. I like the slower songs a little more, the ballads. Well, I like fast songs, but I don't like this song so much. And even with them, it still sounds like a rock song.
Many songs are about love, but usually in the more traditional sense.
On this one, the subject matter is much more, um, traditional. Because he wants to find out whether or not this girl loves him, wants to be with him. That is the same topic that many traditional Latino songs are about. I like it more, too. It is easier on the ears than the Ricky Martin song.
