Open Source MP3 Player
A local player has one job that streaming apps keep forgetting how to do well: open the files already on your disk, read your tags, and respect the way you organized them rather than reshuffling everything into a service's worldview. The open source players here treat your library as the source of truth, playing the formats you actually have and honoring your folders and metadata, so the collection you curated plays back the way you built it.
