how to transfer songs from pc to iphone 5

i was having problems putting music on my iPhone 5s, but then i started pressing the "add folder" button instead of "add files".... seems to be working now... what a relief...! i've only had this phone for 2 years.... it seems to be getting better ;-)

well, i was mistaken... i got music into my library, but i don't know how to get it on my phone.... i just use apple music for music, because i can't put my music onto my iphone. i've never seen someone with a problem get helped in this thread... must be gratifying.

I ran iTunes on my PC, added files to my library, plugged in my iPhone, selected it in File/Devices and selected sync.

Nothing happended.

Help me with my problems of activating sim lock to any network sim and transfer files via Bluetooth or pc

AMEN TO THAT COOLSHREK007
