Question regarding my Playlist project

whatyoumeanbih — Tue, 04 Jun 2024 12:03:38 GMT

Hi,

First of all, I would like to apologize if my question has already been answered, and extend a thank you to the devs for making this such a cool platform to build within.

I am beginning my work on a Playlist building application, it is simple, and rudimentary, but a passion project for my son, and I would love to ask some questions to some of the more advanced members here. I am using the free version of the API.

My goal is to create a playlist for my son, based off the individual tracks in his favorite playlists. He tends to become attached to individual artists and I thought this would be a great way to give him a playlist that features the artists top songs 🙂

In essence, this is how my script operates:

The script fetches the first track from a playlist using sp.playlist_tracks().
For the selected track, it retrieves the lyrics from the Genius API using get_lyrics(). (to add to the description of the playlist)
it creates a new playlist using sp.user_playlist_create().
It fetches the cover art for the track using requests.get().
It uploads the cover image to the newly created playlist using upload_cover_image().
It retrieves the artist's top tracks using get_artist_top_tracks().
Finally, it adds the initial track from the playlist, and the artist's top 4 tracks to the newly created playlist using sp.playlist_add_items().

Ideally I would love to take a playlist, for example his favorite "Internet people" and create these playlists for all 100 tracks inside of that playlist 🙂

However, I am noticing very quickly, that even though I am only testing AND telling my script to take 1 song from 1 playlist, I am running into constant retry-limit problems. Why is this so? And is there anything I am missing or need to fix here in my logic?

Again, thank you so much for taking the time to read this,
- A

Hi whatyoumeanbih, Welcome to the Community!

Nice to hear you are also programming with Spotipy.

Could you please insert a code block with what you already have, and I will have a look at it.

You can insert a code block with clicking on the 3 dots… and then the </> symbol.

Make sure you remove any sensitive information such as the client secret.

As far I got it running, it gets stuck at using the lyrics as a description. 300 seems to be to much. I got it running with 5, but not with 250 characters. So, it is a bit trial and error.
