And why not? If you can play sound that comes from the air, you can play sound that comes from an internal storage card.
Actually, this isn't true.

In order to play an MP3, the device has to be able to download files, maintain a file system, open files, have an audio player and contain the MP3 codec, which is used to convert the encoded file into sound.

A phone that is just a phone doesn't need a file system. The audio codec used in digital phone reception is different than the MP3 one.

So, in order to play an MP3, the phone has to significantly more infrastructure.
