I think that would be close to copyright since the VA of elsa is idina. If they also make her sing let it go, it'll add to the cost of not only the song but the whole thing as well. The production of glee has to pay more to use both the song and the VA. So it kinda makes sense for them not to let idina sing it.
This literally sounds like an echo, if that makes any sense? Like when they sing together, it just sounds like someone put the same audio on top of another and just made it echo. That’s how similar they sound.
Funny how in this Lea has almost the se dress as idina in this video,and notice how they are trying to do songs idina has song? Hmmm so like Lea Is trying to be like idina. I'm a fan of Lea but I don't think she should of song the song by her self if the did a duet it would of been more a Hit.❤️
But Lea doesn't choose what songs are chosen for her as it is a TV programme... And just because they started out the same way doesn't mean she is trying to be like Idina (Lea started out in Spring Awakening and Idina in Wicked)...
