Re: Why can't music players play all of my songs? I keep getting File:"Song Name" is invalid.
Right-click on any song in your iTunes library and click Get Info then click the File tab. Note the location where iTunes is storing your music.
Now, you have several options:
1. Connect your phone to your PC with a USB cable. If you are running the latest Android OS (Marshmallow), you will then need to drag down the notification shade on your phone, tap "USB for charging" (something like that) and then select File transfer mode. If you are running an earlier OS version, the technique will be a bit different. In any event, you should be able to see your phone's file storage area using Windows Explorer. Navigate to your phone's Music folder and simply copy/paste the desired folders & files from your iTunes library to your phone.
2. If you have WiFi in your home, download and install the free version of Airdroid (

Start Airdroid on your phone and it will tell you to open a browser on your PC and navigate to a specific address (Chrome works best, but you can use any browser). Once you have established an Airdroid connection between your phone and PC, just drag and drop files between the two.
