Music is VITAL in my life!

There are only a few things I would change and some things I would have written differently

Music and Me Me and music

I've used 'their' because you don't make reference to gender in the first paragraph (A Person; Someone).  If you had said "Can you imagine a man who is really addicted to music?  A man who...." then I would have said "...moment of his life"

It is difficult for to me to find a moment of the day that music can't improve [or: ...moment of the day that can't be improved with/by music].  Ever because since I was a child, it [music] has been an important part of me. When As I am driving, reading, having a shower or just chilling, I love tunrning on the radio or my mp3 player and listening to my favourite artists or finding out about new groups or genres.

I often prepare [create] some playalists which fit in with determinated  my activities or with my mood.

I often create playlists that compliment my activities or mood.

For example, I love listening to light electronic music when I am absorbed into the story of a   in a good book. When I am working out at the gym, nothing is better than metal and hard rock music!

So, music is really necessary to!   do you mean 'also'? eg. Music is also really necessary (in one's life) - then it would be:

So, music is really necessary too!

or do you mean that it is really necessary in your life - then it would be:

So, music is really necessary for me.

It's my biggest passion and I will never go off it!

Well done!  Hope this helps!
