Of course there are similar apps, just like there are plenty of alternatives to Musicolet. That doesn't mean people should stop developing new ones. I built my app because I wanted to create something of my own, with features I personally wanted to see. Nobody is asking you to stop using Musicolet if it works well for you. As for disabling streaming, that's a fair suggestion and something I can consider. But streaming and local music playback are both part of what my app is meant to offer. Having more choices is a good thing, isn't it?
