This will always be my favourite piece of music from the MCU because it is basically showing Loki's one and only weakness: Frigga. The music perfectly demonstrates the love everyone had for their Queen and how much Loki loved her as a mother especially when this is played when Loki "dies" at the end of the movie. It is saying how much he loved his mother no matter what anyone else said and he regretted not saying he loved her or anything like that during their final talk which I think makes Loki a more relatable and sympathetic character!!
