Ads are the obvious annoyance on Spotify's free tier — but they're not the only thing running in the background. The client also makes a handful of background requests unrelated to playback. BlockTheSpot's config.ini blocks specific ones by name, and reading the actual file tells you exactly what's being cut off, rather than leaving it vague.
The real URL block list
Inside config.ini, the [URL_block] section lists exact endpoint paths the patch blocks outright:
/ads/— direct ad-serving requests./ad-logic/— the logic layer that decides which ad to show./gabo-receiver-service/— an analytics/event-reporting endpoint./desktop-update/— the client's self-update check.
This is a plain, editable list — not a black-box filter — which is part of why it's worth actually reading rather than taking on faith.
Crash reporting and metrics
Separately, the [LIBCEF] section sets Block_crashpad=1, which disables the embedded browser layer's crash-reporting pipeline. And within the JavaScript-bundle patches, a disable_metric entry specifically neutralizes a call to BrowserMetrics.getPageLoadTime() — a page-load timing metric the client would otherwise report. Between the URL block list and these two patches, most of the background traffic that isn't directly about playing your music gets cut.
Why blocking this at the app level matters
A browser-based ad blocker can't see any of this, because none of it happens in a browser — it's the desktop app itself making these requests directly over its own connections. That's the core reason BlockTheSpot works by patching the client instead of running as an extension: it can block requests at the source, before they ever leave your machine. Installing a browser ad blocker alongside the Spotify desktop app does nothing for either the ads or this traffic — the desktop client isn't something a browser extension has any visibility into.
How the patch identifies what to block
Beyond the plain-text URL list, the deeper patches (like the adsEnabled flag flip described in our features breakdown) work by locating a specific byte pattern — a "signature" — inside Spotify's compiled code or JavaScript bundles, then overwriting a small number of bytes at a known offset from that pattern. It's precise and surgical rather than a broad filter, which is also why it can break when Spotify changes its code enough to shift where those patterns live — covered in our troubleshooting guide.
What this doesn't do
Blocking these specific requests isn't the same as anonymizing your account — Spotify's servers still know what you play, since that's core to how the product and its recommendations work at all. What gets cut is the additional layer of ad-serving and metrics traffic listed above. The patch also adds no tracking of its own: there's no separate phone-home behavior, no analytics, nothing reporting back to anyone beyond what's in the public source.
It's also scoped narrowly — this has nothing to do with cookies, fingerprinting, or trackers in a web browser. It only affects the Spotify desktop application, and only the specific endpoints and calls listed above, not features like Spotify Jam, Lossless audio, or lyrics — see our full breakdown of what BlockTheSpot does and doesn't affect.
The bottom line
This blocking comes bundled with the same patch that removes ads — there's no separate step or setting to turn it on beyond the default config.ini. See our step-by-step setup guide if you haven't installed it yet, or our platform compatibility guide if you're not on Windows.
