jakobkraft, you might want to use the "Add to playlist" feature to add a bunch of songs to a playlist, unless you enjoy playing one song and then going back and selecting another song.
😄 The best way to use that feature is to select your first song, pause the audio, add it to the playlist, and then start browsing through your collection selecting songs and adding them to the playlist. When you have enough selected, choose "Start playlist" (and unpause the audio). m3u playlist files are also supported.
As canaws said, the Roku only supports a very limited set of video formats. HandBrake is free and will convert pretty much anything into MP4 format, which is supported.
