My Question or Issue

Hello Spotify Team,

I am reporting a bug that severely affects the integrity of "Your Library." Spotify's "Like" function has a fatal contradiction that forcibly saves the wrong song versions to my "Liked Songs," creating mass duplicates and making library management a mess.

How to Reproduce: How Inconsistent Behavior Corrupts the Library

The core of this bug is that the "Like" function behaves in two completely different ways depending on where it's executed in the app, which directly leads to library data corruption.

Using the album 歩き出すのだ、傘がなくとも。 by Japanese artist 傘村トータ as an example:

• Scenario A: Liking from the Album Tracklist (This pollutes the library)

  1. Action: From the album page's tracklist, I press the "+" or heart icon directly on the track with the Japanese title, 今日も空が綺麗だから.

  2. Result: The track saved to my "Liked Songs" is the INCORRECT Romanized version (Kyou mo Sora ga Kirei dakara). The system ignores my choice and pollutes my library with a version I do not want.

• Scenario B: Liking from the Now Playing Bar (This works correctly)

  1. Action: I first start playing the same Japanese track, 今日も空が綺麗だから. After it begins playing, I press the heart icon on the "Now Playing" bar at the bottom of the screen.

  2. Result: The track saved to my "Liked Songs" is the CORRECT original Japanese version.

Further Testing: Proof the Fault Lies with Spotify's System

I have thoroughly tested this and confirmed it is not related to user settings. The incorrect behavior in Scenario A persists even after I changed my client language to Japanese and used a VPN with a Japanese IP address. This proves the error comes from Spotify's backend, which forcibly applies this flawed rule based on my "account country of registration," thereby corrupting my library's content.

Direct Damage Caused to "Your Library"

1. Library Filled with Duplicates: When a user inevitably uses both methods on the same song, this system bug actively creates duplicate entries (one Japanese, one English) in "Liked Songs," forcing users to spend significant time on manual cleanup.

2. Curation Efforts are Trampled: I explicitly chose to save Version A (Japanese), but the system forces Version B (English) on me. This completely disrespects the user's effort in curating their personal library.

3. "Liked Songs" Feature Becomes Unreliable: This core library function is rendered untrustworthy and full of errors, losing all of its intended convenience and reliability.

Clear Demand

Please fix this library-destroying bug.

I demand that you unify the backend logic for all "Like" buttons to ensure it faithfully and reliably saves the exact version the user chose into the library. What the user saves is what the user should get.

A paying user who just wants a clean and reliable library.

Hi there @chaosu0401,

Thanks for reaching out and for the extensive information you've provided us.

We've noticed similar discrepancies with adding songs to playlists and Liked Songs when multiple versions exist and with the info you've provided us we've been able to greatly narrow down the exact behaviour. We were able to reproduce this, showing that using the plus symbol in the Now Playing View indeed adds the correct version while the plus within albums doesn't. 

We'll happily pass your feedback and all the info you've provided onto the appropriate team. Be advised however that we cannot say for certain at the moment when or if this is going to get addressed.

Cheers!
