Tech n9ne has done some KC Chiefs songs/raps.
Him and other artist, Most of their songs are more less team pride the "we're the best" or "kick your butt" and "color pride"

They can be, yes.
Ex: The Super Bowl Shuffle = dementia. John Fogerty's "Centerfield" = not quite as much. He was being serious about baseball.
On the very same album (Centerfield, Warner Bros., 1985), he had a song about a pig that could pickpocket you. That's insane. But the song wasn't really about a pig, it was about his manager. So, not dementia.
It's all about intent. That said, damn near all songs about sports teams are dementia.
