Tape MP3 without memory

It seems that it has been years since I last used a cassette, and there is still a broken Panasonic Walkman at home. Nowadays, people find it more convenient to download songs using MP3 players without paying any money. So, it becomes harder and harder for singers to make money.

Now, let me introduce you an MP3 in the form of a cassette ($22). It looks very much like a cassette, but it is actually an MP3 player. Its features are not well-known. Just by looking at its appearance and price, you know that it does not have an expensive LCD screen. Moreover, it has a secret: it does not have any built-in storage. You can find an SD card slot at the bottom, which is the key point. You must prepare your own SD card.
