In October of 2015, the service extended to include all YouTube videos, not just music videos. It included music from both YouTube and Google Play Music, and catered to users of both services. The service was limited to participating record labels, who took a share of the subscription revenues. It was called Music Key, and it offered ad-free streaming of music videos. However, it wasn’t called YouTube Premium at the time. YouTube Premium launched back on November 14th 2014. You’ll have to access them via the YouTube app. That said, the videos are saved as EXO or BLOB files, which are unreadable by most software. Quick Answer: YouTube Premium downloads are stored in a different location depending on the type of device. But where are these video files actually stored? One of its best features is being able to download videos to your phone or other device. YouTube Premium is one of the most popular subscription video and music services on the web.
