The differences are as follows:

1. Different formats:

Data CD means that the file type on your computer remains unchanged and is copied directly according to the original file format. onto the CD.

Music CD refers to processing audio files such as MP3/WMA/APE on your computer through the computer to form audio track files on the CD, and then copying them to the CD.

2. Different spaces:

The general capacity of data CD is between 650-700M. Files such as MP3 are relatively small and can copy nearly a hundred songs.

Music CDs generally can only hold up to 17 songs of 3-5 minutes.

CD sound quality has deteriorated:

Reading and writing errors

This type of error is different from ordinary file copy errors. Similarly, it will occur when the source disk is scratched or the CDR disk is of poor quality. At this time, the data is indeed lost. When you use EAC to compare the data on the two disks, you will find that there are obvious differences between the two.

Note that it is a difference, not OFFSET (OFFSET itself only indicates the initial offset of the data and will not cause distortion). The solution to this problem is simple: don't use too bad source disks and CDR disks. If the source disk is slightly scratched, it is recommended to use EAC to capture the audio track. It can be read repeatedly to ensure the accuracy of digital copying.

I won’t go into details on this point. You can refer to the introduction on the use of EAC on Tankexing. And this is not the main reason for the poor sound quality.
