Although this doesn't need a single quote mark, make sure when you do use single quotes you are using the correct character (') rather than the backtick (`)

Because of the song "Summer", I got to know the band named Delapovazhnee. Because of the song "Summer", I got to know the band named Delapovazhnee.

This is fine, but I think "a" band works better than "the" band in this instance, because you are introducing it as a new subject, rather than referring to a subject that's been previously introduced. However, I believe it's still correct the way you wrote it.

Because of the song "Summer", I got to know thea band named Delapovazhnee. Because of the song "Summer", I got to know a band named Delapovazhnee.

It is a Russian band. It is a Russian band.

This is fine, but usually you would say "they are" instead of "it is" when referring to a band. The "they" is basically referring to the members of the band.

It is a Russian band. It is a Russian band.

This sounds perfectly natural to me. “They are a Russian band” would sound slightly foreign (to me).

I really love this song and its band. I really love this song and its band.

What you've done here is fine, but it also sounds a little off to refer to the band as an attribute of the song. Saying something like "I really love this song, and the band in general" sounds a bit more natural to me.

I really love this song and ithis band. I really love this song and this band.

Although I don`'t know how to use ЙЦУКЕН, I want to share some favorite sentences there. Although I don't know how to use ЙЦУКЕН, I want to share some favorite sentences here.

When you say you can't use "ЙЦУКЕН", are you saying that you can't use the Russian keyboard, hence why you need to copy the sentences to langcorrect? This is my guess, because I'm not totally sure what "ЙЦУКЕН" means. This might be a good place to add some context for non-Russian speakers who probably have never heard of ЙЦУКЕН (like me :) ).

I have no idea what ЙЦУКЕН is. Could you explain it in English?

You should remove the space before this quote.

Then there are also many other beautiful songs by this band, such as "Firiday", "Painkiller" and so on. There are also many other beautiful songs by this band, such as "Friday", "Painkiller" and so on.

I am just guessing that the song is called "Friday" and that that was a typo. There is a subtle difference here when you choose whether to start this sentence with "Then", or simply with "There". "Then", in this context, implies a subject that you will be talking more about later, either in the same sentence or in the sentence(s) following this one. For example, "Then, there's this song called "Friday" that's my favorite. I absolutely love it!". In your case, because you are not referring to the songs again to say anything else about them specifically, I would make the correction I suggested here and remove the "then". I hope that makes sense - it's a pretty subtle difference.

Since you already wrote “such as,” you don’t need “and so on.

They are sweet, soft and full of young emotionsthful energy. They are sweet, soft and full of youthful energy.

This sentence is written well but "young emotions" doesn't sound quite right. "Youthful" would work better here, as in my suggested correction.

They are sweet, soft and full of young / youthful emotions. They are sweet, soft and full of young / youthful emotions.

For example, "Seventeen Teenager" is a faun song, and its lyrics touch me a lot. For example, "Seventeen Teenager" is a fun song, and its lyrics touch me a lot.

I am guessing that "fan" should be "fun", unless you're referring to a song made by fans, in which case it would be "fan-made".

"You are the fulcrum where I embrace the moon." "You are the fulcrum where I embrace the moon."

“Fulcrum” seems a bit odd. What are the lyrics in Chinese?

After all, Mmusic knows no boundaries. Beautiful lyrics are always touch everyone a lot. After all, music knows no boundaries. Beautiful lyrics always touch everyone a lot.

"a lot" at the end feels a little redundant, but it is grammatically correct.

After all, Mmusic knows no boundaries. Beautiful lyrics are always touch everyone a lot. After all, music knows no boundaries. Beautiful lyrics always touch everyone a lot.

Be careful of the spacing around punctuation. This is much more important in English than in Chinese.

You know, folk music, such as "Scarborough Fair," is also one of my favorite styles. You know, folk music, such as "Scarborough Fair," is also one of my favorite styles.
