I have the hobby of cracking stuff like that (but mainly windows apps to tell you the truth) and there are many-ish people out there with the same hobby. search around a bit and google stuff like “Spotify Car Thing github” or “Spotify Thing bypass” or jailbreak. Heavily rely on github and russian forums. Also random small blogs
If you’re so determined though and nobody else has done it and you’re fine not using it for 3+ months, there’s a very slim chance that I could find the time to bypass it
