Extremely clean and customizable interface, easy to use, and easily rivals other paid subsonic clients. that said, a few features that can be confusing: - it's a bit unclear that in which mode is the repeat button is; replay at the end of the queue, or replaying the song. - downloading single songs isn't available by default, and it's named "caching", which could sound confusing. but aside from those, 5 stars!

Currently to see all your songs you need to go to search and select songs. Out of all the free players this app has the feature working correctly when you press next it just goes down the list. can't believe it this would be so hard to find. there needs to be more apps catering to people who have massive libraries of track 01 - [unknown artist] album n/a. everything is also in folders.

just found castafiore. it's all I wanted, it could become the de facto music player for subsonic servers. beautiful interface, great usability, user UX customization was a great addition since last update. I'm using ultrasonic because, right now, it is the only app that's free and works well. I only miss the ability to set the number of cached songs and real time cached song icon update

Thanks! Hmm, that’s strange, it works for me. Send me by email which server you’re using and its version so I can test it on my side. You can download previous version on Github or try to delete cache to fix it. My email is sawyer.flink@protonmail.ch
