One last thing re: Lollypop, it is available in MX17 (either Stable or MX Test Repo) so there is no need to install lollypop as a flatpak in MX17, except as a test.
I made the package request quite some time ago, and there was no problem packaging it for Debian Stretch.
I only use lollypop as a flatpak in Debian Jessie (MX15/16) because it can't be backported so far back. Of course, the current flatpak version is the gnome 3.28 one, so my version of lollypop in MX15/16 is actually newer than the version Stevo compiled for MX17. But I actually prefer the older version, since like I said, in the newer versions the developer began hiding some music options, like internet radio, "play random album", etc. and you have to right click to make them visible again.
In Adrian's thread asking for testers to try the MXPI prototype:
he did give a warning about the size of a runtime when you install flatpak apps for the first time.
That is of course one of the disadvantages of flatpak, which is why it is still best to check first to see if a package can be backported by the Packaging Team.
