Thanks for your correction! I want to help you as well!

I like the Beatles

Hello everyone. As (or For) the topic I want to talk about my favorite western music of the Beatles. (I want to talk about my favorite wester music: The Beatles) In China it isn’t the most fashionable (this is usually for clothes or styles) though, it is the most irreplaceable in my eyes. (In China, it isn't the most popular, but it is irreplaceable in my eyes.) The first time I heard Hey Jude (was) when I was in high school. It was covered by Stefanie Sun. Then I inquired on the net to the Beatles, (and) from then on I fell in love with this song. (Then I searched the net for "The Beatles.") and (What gave me a headache) In fact a headache was that I didn’t understand what they are (were) singing about. In these songs I could only understand a few words. This was one of the reasons why I wanted to learn English.
I like theirs songs as Yesterday and Let It Be. My favorite song is While My Guitar Gently Weeps. I almost listen to their music (almost) every day. Now I can sing a few English songs, although I don’t know what (they) mean. Honestly I am very curious about how do I (to) remember the lyrics!

大家好，如题所见今天我想谈一谈披头士的音乐，这是西方音乐中我最喜欢的。虽然在中国他们的音乐不是现在最流行的，但在我眼里它们是无以伦比的。当我上高中的时候第一次听到孙燕姿翻唱的Hey Jude. 然后我在网上查到披头士，自那时候起我便爱上了他们的音乐。事实上最头痛的是我根本不知道他们在唱什么。我只懂几个单词。这是我认真学习英语的一个原因之一。
我喜欢他们的唱的 Yesterday 和let it be，我最喜欢的是While my guitar gently weeps.我几乎天天听这些歌曲。现在可以简单地唱几句。但是我还是不知道意思。坦白讲连我自己也困惑我是怎么记住歌词的。

The Beatles lyrics are very hard to understand sometimes! They talk about some weird stuff. Have you heard "I Am the Walrus" ?? I have been trying to learn some Chinese songs recently. I really like 我的歌声里！ What are some other recent famous Chinese songs?

我也很喜欢 TheBeatles! 你听过 Jimi Hendrix 没有？他也非常好。我只会唱几首中国歌， 但我最喜欢的是崔健的”一无所有“。如果你认识跟 The Beatles差不多的汉语音乐，请告诉我！

You have two wonderful corrections, so I shall translate from your original instead.

大家好，

Hello everybody,

如题所见今天我想谈一谈披头士的音乐，

Today I would like to talk about a topic on the music of the Beatles.

这是西方音乐中我最喜欢的。

This is my favourite western music.

虽然在中国他们的音乐不是现在最流行的，但在我眼里它们是无以伦比的。

Although not China's most popular music of today, they are matchless in my eyes.

当我上高中的时候第一次听到孙燕姿翻唱的Hey Jude.

When I was in high school, for the first time I heard, "Hey Jude", it was Sephanie Sun's translated redition.

然后我在网上查到披头士，

Afterwards, I searched on the internet about the Beatles.

自那时候起我便爱上了他们的音乐。

From this time onwards, I began to fall in love with their music.

事实上最头痛的是我根本不知道他们在唱什么。

To be honest, my biggest headache is that I do not know what they are singing.

我只懂几个单词。

I only knew a few phrases here and there.

这是我认真学习英语的一个原因之一。

This is one main reason that I am studying English so seriously.

我喜欢他们的唱的 Yesterday 和let it be，

I love to hear them sing, "Yesterday" and "Let it be".

我最喜欢的是While my guitar gently weeps.

My favourite is "While my guitar gently weeps."

我几乎天天听这些歌曲。

I listen their music almost every day.

现在可以简单地唱几句。

Now I can sing a few simple words.

但是我还是不知道意思。

Still I don't understand what they mean.

坦白讲连我自己也困惑我是怎么记住歌词的。
Frankly, even to myself, I am puzzled how I could remember the lyrics.
