spotube plays the wrong songs

[snuggle62a]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

It seems that some songs that are published on Spotify but not on YouTube are being played incorrectly.
For example:
https://open.spotify.com/intl-de/track/0JXjmiB33ize81JhqupqJf
The cover image and time are displayed correctly: Here 4:15 .
However, something else is played during playback, here: 2:23:34 .

Expected Behavior

The correct song should be played.

Steps to reproduce

1. I Open the app
2. I search "Reiner Bock We Are Free"
3. I start the song
4. The cover image is correct and the right time is displayed
5. A different song is played

Operating System

Spotube version

The same behavior also occurs with the Flatpak version.

Apparently Spotube does not play content from Spotify, but only from YouTube.
I have noticed that, for example, the song "When You Believe" sung by Kim Schutzius on "The Voice Of Germany" 2023 is displayed by Spotify (2:10 minutes long), but the audio part of the video is played by YouTube (8:56 minutes).

Now the question for me is, is this intentional, and if so, why can't I browse the YouTube content without logging in to Spotify?

Yes, that's intentional. I thought we made it pretty clear in the readme 😅

An open source, cross-platform Spotify client compatible across multiple platforms
utilizing Spotify's data API and YouTube (or Piped.video or JioSaavn) as an audio source,
eliminating the need for Spotify Premium

Now the question for me is, is this intentional, and if so, why can't I browse the YouTube content without logging in to Spotify?

This is because it's strictly a Spotify client. So, it only uses Spotify generated/provided playlists/album/tracks etc. Also, generally, Spotify music collection and YT Music has almost the same amount of tracks (over 100 million) so it's the same data just a bit differently bundled playlists.
Besides, for YT Music, user needs to Log in with Google account for syncing Library, but YouTube's data API has very limited quota. Spotify's API is very generous in those terms.

Thank you for your explanation!
