Ditch Streaming: how to Build a Personal music Server for Your Car
Table of Contents
A growing number of music lovers are reclaiming control of their listening experience by building personal music servers, offering a solution to the limitations of modern streaming services and the dwindling support for physical media in vehicles.This approach allows enthusiasts to enjoy their entire music library on the go,without relying on data connections or sacrificing storage space on their smartphones.
One driver’s frustration with the unpredictable nature of streaming platforms – specifically, songs disappearing from playlists without warning – sparked a quest for a more reliable solution. “I started collecting CDs and vinyl records,” they explained, “but I couldn’t easily take them with me in my car, as it has no CD or record player.” While digitizing the collection was straightforward, the sheer file size and storage requirements presented a new challenge. High-quality audio, whether ripped from a CD or purchased from services like qobuz, quickly accumulates, easily reaching tens or hundreds of gigabytes.
The answer, it turned out, was a personal music server. Unlike streaming services, a music server plays files directly from your own storage, sidestepping the limitations of phone storage. Attaching a 1TB external SSD or USB flash drive provides ample space, with the ability to easily expand storage as needed. In essence, a personal media server functions much like Spotify or Apple Music, but with one crucial difference: you control the library.
Building Your In-Car Music Hub: Server and Client
The setup involves two key components: the server, which hosts the music, and the client, which plays it back. The individual who pioneered this setup chose Navidrome, running on a Raspberry Pi 4, for its ease of installation and use. For those also wanting to store video, Jellyfin is a viable choice.
Setting up the server itself is remarkably simple. The process begins with installing a lightweight operating system – a headless version of Raspberry Pi OS was used in this case – and configuring Wi-Fi settings for SSH access. Without this step, a keyboard and monitor would be required for initial setup.
once the OS is installed, Navidrome is installed via a DEB file download, automating the rest of the configuration. the Raspberry Pi was then configured to broadcast as a Wi-Fi hotspot using the command sudo nmcli device wifi hotspot ssid (Wi-Fi name here) password (password here) ifname wlan0. This allowed for seamless connection from a smartphone. To ensure the hotspot launches automatically on boot, the user ran nmtui, navigated to “Edit a connection,” selected the hotspot, and enabled the “Automatically connect” option.
The final step involved configuring the Raspberry Pi to automatically mount the external SSD and directing Navidrome to locate the music files.
Connecting to your Music: The Client Side
Numerous clients are compatible with Navidrome, but Symfonium was selected for its compatibility with Android auto. Configuration is minimal, requiring only the server’s IP address (port 4533) and login credentials. When using the Raspberry Pi as both hotspot and server, the server IP address is typically the gateway address – in this instance, 10.42.0.1. Users can determine their gateway address by running ip a in the terminal and looking for the wlan0 inet entry.
with the client configured, access to the entire music library is readily available.
While the system currently functions effectively, one area for advancement has been identified: adding new music requires physically disconnecting and reconnecting the storage drive to a computer. The user plans to address this by permanently wiring the setup to their car and adding a second wireless adapter to enable automatic syncing from their home network,eliminating the need for manual data transfer.
