Setting Up a Personal Music Server

A few months ago I set my music free with an instance of the Navidrome Music Streaming Server on Pikapod. It was very easy. I was up and running in no time.

There was an old laptop that I could have used as a server but was put off by the thought of wrangling network settings. I had my fill of that with a Nextcloud instance on a Raspberry Pie some years ago.

Pikapod provides a great service at a good price and profit shares with the developers of the open source apps it hosts. All good. I was happy with the service.

Some time after I learned about Tailscale. It basically removes the pain of configuring a secure network to facilitate remote access to a local server. For my use case it’s free. What’s not to like?

What with an old unused laptop lying around, knowing I could do this and with a bit of time on my hands I decided to go for it. Guided by an LLM it was all quite straight forward. As I am writing this post the process of syncing several hundred GBs of music files to the local server is completing in the background. All working as expected. Streaming on local and remote networks.

Happy days. I’m now one of the increasing number of people whose hosting their own music streaming service.

Here’s a few details -

Server

  • Model: Lenovo IdeaPad Flex 15D
  • CPU: Intel Atom x7-Z8750 (4 cores, 1.6-2.56 GHz)
  • RAM: 4GB
  • OS: Ubuntu Server 24.04 LTS

CPU Constraints

  • No real-time transcoding - CPU will struggle with FLAC→MP3 conversion
  • Solution: Sync only MP3 files, pre-convert lossless formats
  • Limited concurrent streams - Max 2-3 simultaneous users
  • Power efficient: 2W TDP, suitable for 24/7 operation
