I love this app! What's so great about it? You can use it to download youtube videos as MP3s on your kindle! Okay, that may have been a tad bit confusing, but it means that if you have a favorite song, especially one you can't get in the kindle music shop, you can download it as and MP3 and it is added to your music collection. This fantastic little app allowed me to add the music from Emmett Otter's Jug band Christmas to my playlist and I really like that. The added perk is that the app is also free, YAY!
