This may be a separate topic, but this is an interesting article. TikTok has changed how people use music:
TikTok has flipped the script on the music industry, and everyone from artists to analysts and even marketing bosses at the top labels are trying to catch up.

Two things I'm amazed by is how people use TikTok to interact with music, and secondly how dirty the music is. A lot of what I hear on TikTok would never get airplay on the radio.
Having said that, it's likely that TikTok may become more important than Spotify, and that Spotify may be looking for ways to make it's platform more interactive.
