Welcome to Android Central! Is all of that music in your Google Play Music cloud library? If so, then the problem may be that the Nike app is looking for locally stored music files.

Is the Nike app giving you a selection screen for music apps? You could try going to Settings>Apps, then tap Menu>Reset All App Preferences. Now go back to the Nike app and add a music player -- does it give you more choices now?
