Giocoso is the gapless, trackless, optionally-randomising, optionally-scrobbling command-line FLAC player for Linux, Windows and Raspberry Pi.
Version 1 was released on 15th July 2021 and received 13 point releases in the following months, and only ran on Linux. It can still be downloaded from the software archive page, but is no longer under active development. Giocoso version 2 was released on July 22nd 2022 and can still be downloaded from here, though since it too is no longer in active development, it is not recommended to use it further.
The latest and current version is Giocoso Version 3, which was released on November 22nd, 2023. It is recommended you switch to using Giocoso Version 3 as soon as possible. Follow the instructions for doing so in the Version 3 User Manual. Fresh installations of Version 3 on various platforms are also described in the User Manual.
Note that whilst Version 2 could run on MacOS, Version 3 does not do so.
Solus Linux is similarly not usable for Version 3, though it was in Version 2.
