How to upload music on to Micro SD card from Windows Media Player?

There are multiple ways to upload music onto Micro SD card:

• The easiest way is if your gadget allows you to use a USB cable to upload any files.
  
• Use a card reader that supports Micro SD cards (or SD cards and Micro SD -> SD adapter)
  
• If your gadget supports wireless connection (BlueTooth, Wi-Fi) you can use it to upload music files. You will need a Wi-Fi or BlueTooth adapter for your computer. Please also note that old mobile phones are very slow at transferring large amounts of data via BlueTooth.
