These aren't actually the "official" remixes from her original music because its sounds a lot different. But they are official because its on the cds, but I cant find them anywhere..I think you can only buy them online. Violet F - Sweet Lessons are instrumental albums that covers a lot of Kpop songs. Its sounds like midis but better.

The mix you're listening to is shorter, so thats why I want to get the full single versions.
