I use my Vero almost exclusively for music, mostly FLAC files but also some MKV files of blu-ray music and concerts. It has separate Music and Video sections on the menu, although there is some overlap in accessing the files. It can create, or at least play, playlists, but I don't use that function. All my FLAC files are tagged with album art that displays during playback. It is true that a lot of people use this unit for video, but I'm not one of them.

But, because I like things simple, I try not to dive into the deep end too much. Having said that, another good thing about the Vero is the ability to get support both from its developers and its community. I had some set up questions when I first got it, and I found that forum really helpful.
