How to get music onto samsung intercept android phone (has issues)

Okay, so the said issues are that the phone is not recognized on my computer when plugged in via the usb cable (however it still charges fine on the computer), and the downloadable drivers do not rectify the problem. I have tried using wifi to transfer the songs, but the wifi has issues as well. I need some way to get the music onto the micro sd. Does anyone know how to do this, maybe with an app that transfers the files over a network or something? Once again, wifi and connecting to the computer are out of the question. I also dont want an app to download music, I just need to transfer the songs.
