Is TikTok the future of the music industry? Who'd have thought that a video plaform could be the key to bringing classic songs into modern day fame? Thanks to TikTok, one of the world's most popular social media apps, this is now very much possible. Take Metallica's "Master of Puppets" for example: After being featured in Stranger Things' finale Season 4 episode and becoming a hit on TikTok soon afterwards, it shot up onto Spotify Viral 50 as well as Billboard Hot 100 - over 30 years after its original release! Who knows what other legendary tracks we can expect making comebacks thanks to creative uses on platforms like these.
