I'm in have been listening Western musics recently. I'm have been listening Western music recently.

We never really pluralise "music". You would just say "Western music". You could however say "Western songs".

EI especially, I like Justin Bieber 's songs. I especially like Justin Bieber's songs.

I think it doesn't sound very natural to start a sentence with "especially".

When I scrolled my phone, In found thea short video thatwhere kids were singing a famous Western music song, and I wasbecame intersested in Western musics. When I scrolled my phone, I found a short video where kids were singing a famous Western song, and I became interested in Western music.

The --> refers to a specific video, which you have already mentioned or is obvious. Since you are introducing it for the first time in this sentence, it would make more sense to just say "a" here, then "the" in future sentences. A video WHERE or IN WHICH --> when describing what happened in a video, book, movie, etc. Examples - a movie where a knight slays a dragon, a book where the bad guy wins, a video where some kids prank each other, etc OR A movie in which a knight slays a dragon --> this is also correct, though a lot more formal I became --> I figured you were the describing the moment your interest first began, so "I became" makes the most sense here

I am listening to "STAY ", a song by Justin Bieber's, during study time. I am listening to "STAY ", a song by Justin Bieber, during study time.

To write ABOUT Unfortunately English has a lot of phrasal verbs, and some verbs don't work just on their own Some links: https://www.grammarly.com/blog/parts-of-speech/common-phrasal-verbs/ https://www.languageforlife.es/wp-content/uploads/2013/10/Complete-PV-list.pdf For "write" specifically, you can write about (describe a topic), write down (write some words on some paper), write to (address something to someone in particular), etc To be at home --> to be inside your house, to be home. It's a super common phrase, eg. I was at home then, I will be staying at home this weekend, a stay-at-home mother I am having --> present continuous, to indicate it is happening to you right now
