What I see is amazing. Sea Shanties that were mainly for seamen and some German metalheads became popular again, suddenly everyone knew Wellerman, there were tons of covers, everything.
Remixes, something that YouTube long ago forgot about (probably copyright laws, those tend to stifle creativity) are commonplace, people build on releases of others over and over again, creating a completely new and amazing endresult.
What I see from TikTok, is a return to the creativity of years ago.
edit: Because people thought of established artists when I mentioned remixes, I’ll clarify. I mean taking some person singing or playing an instrument, adding yourself playing guitar, putting it to the side of the original and releasing it. Then the next person adds a violin. And so on. Just non-commercial remix culture.
