Here are some other issues with popular songs:
Avraham Fried’s ‘Ish es reayhu yaazoiru ulochiv yomar chazak’ is from Yeshaya – a reference to Goyim exhorting each other to rebel against Hashem.
Carlebach and other’s ‘ Hinei yomim boim neum Hashem v’hishlachti ro’ov bo’oretz lo ro’ov lalechem v’lo tsomo lamayim ki im lishmoa divrei Hashem’. This was one of the severest and harshest nevuas that there will be nobody who will be able to teach Torah (see meforshim there)
