Hello,
I’ve been using mt-daapd for several years now (since well before it was called Firefly), and it occurred to me I’ve never given any feedback about how great it is! I currently have 29000 tracks served off a NSLU2 running Debian which I play using iTunes on a laptop through an Airport Express, and honestly I’ve never had major troubles! Admittedly, I guess I’m an advanced user since I’ve installed vanilla debian instead of unslung, I build nightlies from source by hand, etc.
The reason I started using this for my music was to have an airport-capable music library that I can tag and manage using Musicbrainz (I don’t like the way iTunes can’t sync its library to a directory, but it’s the only player that supports the airport), and it’s been perfect for that. Tag stuff with Musicbrainz, hit the scan button in the web ui, and I am good to go (eventually, the NSLU2 is not exactly a speed demon at 266mhz even with the underclocking resistor removed)
Outstanding work!
