Songs which disappear

There are few songs (HOLD ME by Cam Rao / Don’t let me get too low by Silverstein bur also others…) which disappear in my listening history during a certain period of time. And because of that, they don’t appear in my top spngs. For example, Don’t let me get too low by Silverstein was my most listened song in 2025, but now when I choose from 1st of january 2025 until 31st december of 2025 it appears way lower. Why is that ?
