MIUI Music Not Installing

Hi! So I'm using a Samsung galaxy a3 running android 5.0.2 non rooted. I was trying to install the apps MIUI music anf Amazon underground. Whenever I tried to install Amazon underground, I got the message "app not installed" with only the option *done" after about 5 seconds, and the same with MIUI music. So I uninstalled a few apps that I thought may be using the problem, and I was able to install Amazon, and reinstall them after. But when it came to MIUI music, it still wouldn't work. I've heard of a problem on lollipop not allowing 2 apps with the same permissions to exist on your device, so could this be it? I do have other music apps such as Spotify, deezer(both patched versions) and TinyTunes. I would greatly appreciate any help here.
