4th Gen iPod Touch music app is going haywire.

Question

Recently my 4th Gen iPod Touch (version 6.1.6 recently updated) refused to sync any music. I have had it synced to my computer for more than a year and have been adding new music with the 'Autofill' option. However, last night it refused to sync music. The songs are visible on my iPod but greyed out. This has happened before. Usually it will sync eventually but this time is different. Around the same time my iPod was claiming to be overcapacity. I looked up solutions but none seemed to be particularly helpful. I did delete some music and videos off my iPod to no avail.
Eventually the problem seemed to fix itself with the overcapacity claim disappearing however the data then began to inflate and adjust itself out of nowhere. It would claim my music was taking up 30gig before saying 4gig. Everything seemed to be going haywire with the data reading. When I checked the music app the artists tab claimed I had no music. I selected a song and discovered that it wouldn't play but rather start shuffling in the playlist. I can't do anything to stop this. I have turned the iPod off and on and soft reset it (I think, I held the Power and Home button for several seconds) but the actions have done nothing. it is incredibly confusing as the iPod is only 2 years old and I would like to avoid buying a new one. I'm not sure how helpful a restore or reset would be but I will try it if there is no other option. I've searched the net for an hour trying to find out if anyone has encountered the same problem. Everything else works fine except for Notes which stopped opening months ago. Incredibly confused and would appreciate any help or advice.

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>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:
