Can someone help me with this. As I am new to iPhone and itunes. I have couple of songe (audio format) downloaded from internet and added into "My Music" in itunes. I have synced my iphone 5 with itunes in my PC. But on iPhone where these songs would have been downloaded?? When I go to the itunes tab on iphone 5 it takes me straight to it main page and if I go the downloaded ones then that one is empty.
The iTunes app on the iPhone is for browsing the iTunes store. The Downloads tab there only shows you songs that are currently being downloaded from the store. If I understand correctly, you're tapping this:
Check the Music app on the phone instead - synced music should show up there:
