Use ASP to operate MP3 tracks

Let's briefly talk about the ID3 mark of MP3, because it is mainly used to perform this operation.

At the very beginning, MP3 didn't have the information we saw today, such as singers, ages, and albums.

Only some simple parameters such as yes/no are used to indicate whether it is privated or copyrighted, which makes it inconvenient for MP3-related work, in 1996, a foreigner proposed to append a piece of data to each MP3 file to store the above information. Later, it developed into id3 v1, which is now 1.1 as far as I know, check the details by yourself.

I still get used to using metadata to introduce DLL. I have posted some articles before. If you do not know, please check it yourself.
