Hi, recently I have started to listen to BTS.

However, I found it to be addictive.

I'm assuming this is what you meant by "an easy task" but I may be off the mark.

Since “unique” starts with a Y sound, we use “a” instead of “an.”

This sentence would work better as a continuation of the above sentence.

I’m taking liberties here to setup up your next few sentences.

Taking more liberties here, sorry.

It's more natural to say that you're in a vicious cycle of not remembering who the members are.

the semicolon (;) links two independent clauses that are related.
Put a comma before the 'but' when you are linking two independent clauses.

Listening to new music

Hi, recently I have started to listen to BTS.

I know it is not an unique music gendere.

It may seem odd, but we would probably say "a unique", not "an unique". This is because "unique" begins with a "yoo" sound - "yoo-NEEK" - and that registers to us as a consonant. The sound matters more than the letter, same with words like "an hour".

Also, "gender" refers to being either a man or a woman (well, it's actually more complicated than that, but that's a topic for another time). I'm pretty sure you meant "genre".

However, I found it addictive.

I wanted to know their names, a. An easy task.

Some alternatives:
"I wanted to know their names, which was an easy task."
"I wanted to know their names, and that was an easy task."

FHowever, faces are the actureal problem, s. Sometimes I can see the difference, but when I watch a new video I am lost and confused again, trapped in a vicious cirycle.

"Actual" works perfectly, but you could also use "real", which feels a little more common to me.

"Circle" and "cycle" are similar words, but "circle" is literal geometry, while "cycle" is only a metaphorical circle: a loop of events.
