The first one reminds me of an Italo-Disco tune, but I can't quite place it.
(
edit: I may have been thinking of Bruton's "Heart of Stone" (Wade-Falquero).)
I can't help you with the music, but I have some useless trivia nevertheless ---- the grunts of the men at the beginning of the video are sound bites of Minnesota Viking defensive end Jim Marshall.
Haha, fantastic little tidbit!
I have no idea what it is, but that house song in the second video is great!
