I like that it is easy to use, has many different features and allows me to create my own playlists as well. The fact that you can add your favorite music to any playlist is great! It's also nice having all of the videos in one place instead of searching for them across multiple services (such as Youtube). There really isn't anything bad about this service at this time. Honestly, if there were something wrong I would certainly let them know so they could fix it. We are able to share our content easily by creating playlists for our students. They love being able to listen to their favorites or even just have some background noise while studying.
