Before you burn an MP3 CD, you should definitely check whether your CD player is MP3-capable. One minute of playing time requires around 1 MB of storage space, which means that a CD with 700 MB of memory can play for 700 minutes. MP3 files are a lot more space-efficient. This is perfectly adequate for an artist's album CD but rather unsuitable for someone who wants to have a self-burned CD with as many songs as possible. Usually, only about 20 songs fit on a CD. The problem with this type of file is that it takes up a lot of disk space. But what is the difference? An audio CD stores songs in the CDA format, the same format used on commercial music CDs.
For music CDs, this is usually either CDA or MP3.
The songs stored on it can have different formats.
