MP3 files transfer to android through USB
I have created a PC application using java where I manipulate MP3 files. I want to now transfer these files into the android phone through usb from my application.

I would really appreciate if someone could write me some keywords so I could start looking into.  

So far 
- I have come across "adb push"
- and some wireless and bluetooth (Not relevant to me since I am looking into USB)
- I watched some youtube videos of how its done manually just like an external memory, You copy and paste the music folder into the android memory card I think. 

So I am only looking for the key APIs or something to start reading on. Thank you
