The importance of music

Because I don't have a good topic on my mind, I will talk about the importance of music in our lives. It truly is useful, because it makes us feel better. What would the world be like without music? I don't know and I don't want to know. I think it would be awful. Can you imagine that? I think we would be in such a deep depression. That's the reason why there are so many types of music: rock, r&b, raggaeton, du]bstep, classic, rap, hip-hop and so on. Right now I'm listening to some music and I have to admit that it relaxes me. In many situations, music makes me feel nervous. It depends on my mood.
Anyway, music represents an important part of our lives, in my opinion. Does anyone have another opinion? =D

[Excellent.  I agree.  If you are going to use 'such', it is usually followed by 'that ...'.  "He is such a lazy person that he never arrives on time."  Or, you can use it for emphasis.  "He is SUCH and idiot!"]

I generally choose death rock combined with the Double Violin Concerto in D minor - Second movement: Largo calm to listen, feeling as if shuttling between heaven and hell.
