See the detailed Installation Guide and Last.fm Authentication Guide.
Foo Scrobbler (foo_scrobbler_mac) is a native Last.fm scrobbling plugin for foobar2000 on macOS. Submits tracks based on precise playback rules, caches scrobbles when offline, and operates silently after one-time authentication. Built using the official foobar plugin API, it focuses on reliability, low overhead, and correct metadata handling. Fully open-source under MIT Licence.
Supports macOS ≥ 11.5 on both Intel and ARM.
This is the GitHub site of the macOS version.
For the Windows version of Foo Scrobbler see here.
-
Native macOS Last.fm scrobbling, built specifically for foobar2000
Fully integrated with foobar2000 for macOS. No compatibility layers or wrapper apps. Not a port. -
Rule-based submission logic
Scrobbles only when playback is meaningful (e.g., ≥ 50% or ≥ 240 seconds). -
Automatic offline caching
If Last.fm or the network is unavailable, scrobbles are stored and submitted automatically later. -
Accurate “Now Playing” handling
Fully aligned with Last.fm Scrobbling 2.0 API specifications. -
Minimal user interaction
Authentication required only once. -
Lightweight and efficient
Runs inside foobar2000 without performance loss. Not relying on third-party dependencies. -
Strict playback validation
Prevents malformed or duplicate scrobbles. -
Open-source (MIT License)
Transparent and extensible.
Install foo_scrobbler_mac.fb2k-component from within foobar2000 by pointing to it (that is, add via '+') from the components section.
Authentication requires only an active Last.fm account. Users grant access once through the Last.fm website with their account, after which Foo Scrobbler runs quietly in the background and submits track information automatically. If authentication is cleared from the menu, the same user —or a different one— must grant access again through browser redirection to the Last.fm website. Foo Scrobbler adds a simple, convenient and non-intrusive last entry under Playback in the menu bar. More options are located in Preferences → Advanced → Tools → Foo Scrobbler.
