Frustrated by Locked Out YouTube Account

I've been logging into my YouTube.com channel with my email address for the past two years, but I can no longer do so. My entire music collection has vanished, as has my account. I urgently request that this matter be resolved. Previously, I could log in using a regular account and find my songs, but they appear to have vanished. This is a very frustrating situation, and I'm at a loss for what to do. My music library is very important to me, and I want it back. I never expected to have such a problem with such a large platform as YouTube. I've tried everything to regain access, but nothing has worked. I need help from YouTube's support team to reclaim my account and music.
