Kenny Loggins-The movie song god

My wife and I went to Sonic tonight and I'm Alright was playing over the loudspeaker. Then naturally I started thinking about Kenny Loggins and his other movie songs Footloose from Footloose (duh) and Danger Zone from Top Gun. I thought that it was interesting that one man wrote big songs for 3 of the biggest movies of the eighties. I guess that it shouldn't be surprising considering Henry Mancini, Dave Grusin, or the like, but I don't know many people who go out and but their records. I take that back, anyway I don't hear their music played on the radio. Also I don't know of popular musician who has been around for so long and yet is mainly known for 3 super famous songs. I know that I have probably offended the individual that knows every Kenny Loggins tune ever written, but hey I've heard other Kenny Loggins songs, but I don't know other Kenny Loggins songs. Survivor has 2 big movie songs that I know of from Rocky (numeral unknown) and the Karate Kid, but I know more their music. I guess there is no point to this, but I think that it is a musicological oddity.
