In the Name of G-d

One of the Ten Commandments is the prohibition of saying G-d's name in vain, and after watching this video (see 1:48, whe they say E-L) I realized there are two approaches to this prohibition when it comes to music. All Yeshivish singers I know refrain from mentioning the Shem Hash-m, using the permissible "Hash-m" instead. That includes Shwekey, Lipa, MBD and so on.

On the other hand, many Israeli singers - Chaim Israel and Gad Elbaz for example - sing the Shem Hash-m frequently in their hit songs and I'm wondering what is the Halachic approach to this.

The same thing happens when people sing Shabbos Zemiros. Some are very careful not to mention the Shem when singing Tzur Mishelo or Kol Mekadesh for example, while others say the Shem Hash-m without any hesitation. Is there a difference between singing Zemiros with Shem Hash-m or singing modern-day songs with the Shem?

In my mind, there's no difference since Zemiros are no different than songs we sing today. Many of the composers of common zemiros were just good poets and not necessarily Rabbis. According to this, there's no difference between the songs of Donash Ibn Lavrat, composer of Dror Yikra, and Chaim Israel when it comes to saying the Shem Hashm.

If you look in the Zemiros it's often clear that the poets had in mind the actual Shem Hash-m, and not the substitute "Hashem". Let me bring a famous example:

צור משלו אכלנו ברכו אמוני
שבענו והותרנו כדבר יי

The rhyme אמוני/ יי only works if one mention's the actual Shem Hashm in this song. If you just read יי as being "Hash-m" the rhyme falls apart. So it's clear this song was always sung with the actual Shem Hashm.

But this is not a good Halachic point because maybe the poet was just wrong. I don't even know if he was a Rabbi. Whoever has an answer, please speak up!
