Hi Dani!

I love music of all genres too! I've always got songs accompanying different activities. 

I've gone ahead and made some minor edits to your passage: 

First Entry- Music [1]

Hi everyone, this is my first entry, and I wanna (want to [2]) learn more about english (English),. I propose in this entry talking about music in this entry,.

I like all music, but especially electronic, hip hop and rock music,. what (What [3]) is you favorite music? who (Who) is you favorite singer or band ? if (If) you wanna (want to) leave a link whit (with) your favorite song, that would be great.

[1] The hyphen in this context '-' gives the title a better flow. Moving forward, if you want to change your subject title from music to e.g. food, you can title it as 'Second Entry - Food'. 

[2] Using 'wanna' is completely acceptable in casual English conversations :) 

[3] Great effort all in all, but do take note of punctuation, and also capitalisation when beginning a new sentence. 

Best of luck!
