I have now cleaned up my page to make it look more professional. I haven't decluttered my page for a long, long time. But what I forgot was that I wanted to spare 3-5 more tracks, the ones with the most play counts, and make them private. I accidentally deleted them.
I have researched this topic already and I can see that you normally dont restore tracks for users, only for, well I forgot for whom. But I thought since Im such a loyal and longtime user that maybe it would be possible to make an exception...? It's only for the few tracks that had the most play counts.
