You can simply transfer your music tracks to your smartphone right from your PC or Mac desktop. Find the location where your music is stored – usually under a logically titled folder – and connect your Android phone with a USB cable.
Drag and drop
Drag and drop the tracks you’d like into your phone’s ‘Music’ folder. You don’t need to create new folders for artists or albums – the Android OS should automatically catalogue them later. Transfer over USB should be pretty quick, even for lots of music files.
When the transfer has finished, unmount your phone and disconnect the cable. Open up your Music app. The phone may take a little while to index the new tracks the first time after a transfer, but they will open up instantly after that.
Find the tracks
Your tracks should appear ordered alphabetically via Artist but you can also change the view to Album or simply Songs. Tap on an name to view that artist’s albums. Tapping a track will start playing the music you copied across. Simple!
