Putting music on your iPod using Windows normally require having to use iTunes, which can be a real pain in the but if you hate using extra software for something that should be as easy and dragging and dropping.
But using a cool trick, you can add music to your iPod in the easiest way possible without being bogged down with iTunes.
Start by plugging in your iPod. Make sure that iTunes is not running—if it opens automatically, simply close the program.
Open My Computer, either through an Explorer window or through the Start Menu. Now double-click on the iPod, then select Tools -> Folder Options.
Go to the View tab, then check the option for "Show hidden files."
You'll now see a folder call "ipod_control"—double-click to access it, and simply copy or drag and drop your mp3 files into it! That's it, now you have music on your iPod without ever having to use iTunes!
