can't see my music on my ipod touch

Try:

- Reset the iOS device. Nothing will be lost

Reset iOS device: Hold down the On/Off button and the Home button at the same time for at

least ten seconds, until the Apple logo appears.

- Unsync/delete all music and resync

To delete all music go to Settings>General>Usage>Storage>Manage Storage>Music>Tap edit in upper right and then tap the minus sign by All Music

- Reset all settings

Go to Settings > General > Reset and tap Reset All Settings.

All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.

- Restore from backup. See:

Restore your device from an iCloud or iTunes backup - Apple Support

- Restore to factory settings/new iOS device.

So if yo restore to factory settings/new iPod on this computer you can't sync any music to the iPod?

Does any media like apps or photos now sync to the iPod?

Do the songs play OK in iTunes in the computer?
