Agree! Oh! I grew up listening to Delilah - we had a Tom Jones vinyl - still remember the cover - Tom lounging in a robe like a king. What a voice! And of course BhoRap is a classic :-)
As you rightly pointed out, most people do not even know the lyrics and just enjoy the chorus because it is great to sing something together!
We have authorities here who constantly whine about scenes and lyrics of songs. Funnily, I think the ruckus makes the songs more popular!
