My Thoughts On.... Musical Opinions

Hi again,
  So, music. Everyone has something to say about it don't they? I mean, you could like pop, rock, indie, jazz, classical, dance... The list is endless, and no matter how much you try, you'll inevitably (at some point) get caught in that tedious argument of the best artists and songs.
  Personally, I am a huge fan of the band Lawson. I find them so new, fresh and I could listen to their music all day to be completely honest! I also love Emeli Sande her songs and voice are my version of incredible-or in french, elle est un plein de talent! As I learnt this morning at school. Actually I'm not even going to start on the artists I like, 1. because there are so many artists that shape my life and free time at home 2. because it would create an opinion war somewhere about my opinions, yours and others. 
  Anyway, continuing with music. Why can I not understand some people's love of heavy metal?  To me, it seems like a load of rhythm-less, tuneless crashing and screaming. I like music that has emotion, tune, a beat and a great melody/harmony-so, no, this is not my cup of hot chocolate as I say. Cependant, to many people, heavy metal probably sounds amazing, full of structure, emotion and everything else that makes a good song, c'est la vie...
It may just be me, but does anyone have a friend that has introduced them to a completely new style of music? I have two. The first, my dear friend Emily, who is very unique, funny and has a character and look that stands out from the crowd. Her music consists of people sch as Canterbury, Imagine Dragons, Kyla La Grange and Dive Bella Dive. The first three I was skeptical about but now I am a HUGE fan-Dive Bella Dive not so much, it crosses my, what I call, musically opinionated line. It's strange how one person's musical opinions (that were, what they thought, very restricted and opinionated) can be opened up so massively by a few recommendations from one of your mates, who you thought you knew so well, whilst secretly they live a life of indie rock music. Secondly, my friend Jacob (who I sat next to for a year in french class). He is a stunning guitarist, and quite frankly, musical genius. Artists he likes include Eric Clapton, Led Zeppelin and Elbow. I was sitting there a bit like huh?... But after listening to some of the songs I actually found I really enjoyed the music! So thank you to my friends who have given me a tour of music that isn't just pop in the charts.
I hope you enjoyed reading this, thanks if you're still here!
If you have any musical opinions to share, please say in a comment, thank you.
