Are basic posts effective?

Scrolling through Tiktok or reels, you’ll typically see a bunch of small artists posting slideshows with captions like “imagine if you saw Sabrina Carpenter before she was famous” or “it’s just a song? The song:”. You know the ones. In trying to market my own music, I can’t imagine this being effective in growing an audience or even getting passive streams, but I’ve also see artists I follow build quite a following off of making only these posts. I’ve also heard people say not to reinvent the wheel with marketing and if you see something work for others, it’s a good idea.

What do y’all think? Is this a good strategy?
