Just checked again, looks like a valid audio file, except...

Stereo track, will not work with blockland.
When porting an audio file for blockland make sure to select "Tracks => Stereo Track to Mono". Blockland only accepts mono Ogg Vorbis audio files
Not to mention that this is looped incorrectly, I would recommend more practice before posting.
Edit:
Here is a smoother loop of #Selfie, Same area of the song just, smoother.
