This tweak makes Spotify think that you have a Premium subscription, granting free listening, just like Spotilife.
Several months ago, Spotilife, the only tweak to get Spotify Premium, stopped working on new Spotify versions. I decompiled Spotilife, reverse-engineered Spotify, intercepted requests, etc., and created this tweak.
Please refrain from opening issues about the following features, as they are server-sided and will NEVER work:
- Very High audio quality
- Native playlist downloading (you can download podcast episodes though)
- Jam (hosting a Spotify Jam requires Premium, joining by link currently works only with Jailbreak/TrollStore)
EeveeSpotify replaces Spotify monthly limited lyrics with Genius. If the tweak is unable to find a song or process the lyrics, you'll see the original Spotify one. The lyrics might be wrong for some songs (e.g. random language translation, article, another song). This is due to how the tweak searches songs on Genius. While I've made it work in most cases, kindly refrain from opening issues about it. Genius lyrics are also not and will never be time-synced.
In theory, implementing downloading/offline mode locally should be possible, but it will not be included in this tweak.
Upon login, Spotify fetches user data, including active subscription, and caches it in the offline.bnk file in the /Library/Application Support/PersistentCache directory. It uses its proprietary binary format to store data, incorporating a length byte before each value, among other conventions. Certain keys, such as player-license, financial-product, and type, determines the user abilities.
The tweak patches this file while initializing; Spotify loads it and assumes you have Premium. To be honest, it doesn't really patch due to challenges with dynamic length and varied bytes. Ideally, there should be a parser capable of deserializing and serializing such format. However, for now, the tweak simply extracts the username from the current offline.bnk file and inserts it into premiumblank.bnk (a file containing all premium values preset), replacing offline.bnk.
Tweak also changes query parameters trackRows and video in HTTP requests to true, so Spotify loads videos and not just track names at the artist page. Sorry if the code seems cringe; the main focus is on the concept. It can stop working just like Spotilife, but so far, it works on the latest Spotify 8.9.## (Spotilife also patches offline.bnk, but it changes obscure bytes that do nothing on new versions). Spotify may reload user data, and you'll be switched to the Free plan. When this happens, you'll see a popup with quick restart app and reset data actions.
