Consider calling them platitudes.

platitude noun A remark or statement, especially one with a moral content, that has been used too often to be interesting or thoughtful. ‘she began uttering liberal platitudes’ - ODO

A platitude is a trite, meaningless, or prosaic statement, generally directed at quelling social, emotional, or cognitive unease. Platitudes are geared towards presenting a shallow, unifying wisdom over a difficult topic. However, they are too general and overused to be anything more than undirected statements with ultimately little meaningful contribution towards a solution. - wikipedia

This word carries a lot of specific connotations that your friend probably don't want for his/her album, but the (quite new) idea of slacktivism could be fairly well described that way.
