Why can't I copy music files onto my phone from my Windows 7 PC?

make sure your phone firstly has enough storage and secondly that your phone is in 'hard drive' mode or something similar where you can transfer files. drag them to a music folder and it should work. and when you say it does nothing, do you absolutley mean that? like there's no pop up, no progress bar, no error screen, nothing? good luck, I have had a lot of problems with copying files from my computer to my android phone just because the wires in the usb cabe are very poor, even though they came with the phone. try jiggling it around until it actually connects then keep it 100% still
