How can you put music on your micro chip from your computer?

The micro chip is assumed to be inside a device. To upload music directly into a micro chip would be impossible. If the micro chip in a device was built to store data you simply have to send the music into your device. Usually, devices that can store data are pendrives, MP3,MP4 players, cell and smartphones. Sorry, but your question is not so clear. May be you are talking about micro card.
