iTunes skips through every song [SOLUTION] [SOLVED]

Look, I'm just posting this so that people searching for a solution here can find it via search in the coming days/months/years, as I could not find any help anywhere for this issue.

The problem, is that when trying to play a song, iTunes (windows10) will attempt to load for like a fraction of a second and then skip to the next song, and continue to do this...skipping song after song until it reaches the end of the album or playlist.

When trying to re-authorize my computer within itunes as an attempt to solve, I found i was getting an 42110 error. Then after solving that, I was also getting a 45054 error. The solution was to delete two folders called 'SC Info' and 'adi'. Then to essentially, deauthorize/reauthorize and sign out/sign in with iTunes. Detailed instructions and source info below:

  1. quit itunes
  2. press windows key
  3. in search bar type "%ProgramData%" and click on the folder matching that name that pops up
  4. show hidden files (windows10: click 'View' and check the box 'Hidden Items')
  5. Open the folder 'Apple Computer' and then the folder 'iTunes'
  6. Right-click and delete the folder 'SC Info'
  7. Right-click and delete the folder 'adi'
  8. Restart PC
  9. Open iTunes
  10. Deauthorize your device [Account -> Authorizations -> Deauthorize this computer]
  11. Then 'Authorize this computer' from same location
  12. Account -> Sign Out
  13. Sign back in
  14. Wait for all your iCloud music to load back up
  15. Hope for the best!

I got this after realising I was getting a 42110 error when trying to reauthorize my computer. The solution in this link has most of the steps I put forward above.

However, after following the steps in that link, I got error 45054. So I found this info (which suggests to also delete the 'adi' folder)

Then I just had to do the reauthorization and sign out/in. Working perfectly now! Hope it works for you too!
