so for all I know pshat in the Shlah and the Shaar Hatziyon is that such songs likely contain messages in the lyrics which could be damaging.
Additionally, the MB says specifically, that love songs are assur anyhow.. Which strongly implies that its the tune that is damaging.
If you’d like to suggest people not heed the Chofetz Chaim’s and the Shelo’s advice, which they say will create a bad nature within [even] a baby, fine. But please be upfont about it.
