Show HN: The soundtrack machine that creates a unique playlist with one sentence (feelsapp.io)

Yoo HN —

I just launched my app Feels based off weekly playlists I’ve been making since Feb 2021!

I’ve created 100+ playlists up to this point and realized that these playlists are actually pretty sick, but creating them every week is no easy task lol.

Now there is an easy way for everyone to make their own “Weekly Feels” playlist. You’ll get a generated title, description, image, and 15 songs that are all based off your one sentence.

How does it work? Uses ChatGPT + Spotify recommendation API to get recommended artists, generate a Spotify title + description. Pretty cool tech used in a cool way!

Check out some playlists Feels has already created: Metalcore Mayhem -- https://open.spotify.com/playlist/19rGQ2QR7VDV1NJtPGu9Vg?si=...)

Baby Shower with Tay -- https://open.spotify.com/playlist/0KavjYM8amQIClB54Y72Xe?si=...

Ty for checking it out and would love any initial thoughts on this thing! If it’s shit lemme know!

Awesome idea and great implementation!
yoo thank you so much!

appreciate you checking it out :)

I've been trying out some more things and I think you might have to do some more prompt engineering for ChatGPT.

Prompts sometimes result in valid results but sometimes in a SyntaxError "Unexpected token 'A', "An error o"... is not valid JSON". I also encountered other SyntaxErrors like "the string did not match the pattern". I would guess this might be related to invalid requests to the Spotify API.

Also, it is possible to directly communicate with ChatGPT. Its responses are then output through a playlistContentFormatter error.

Hope this might help. And still, great product!

appreciate it!

yaaa this error is actually from vercel lol. timeout after 10s unfortunately. upgrading to pro rn to fix!
