MelodyQuest

At first glance, MelodyQuest may seem like a simple tool for downloading links from YouTube, but that's not all it does: it also downloads songs from more than 200 video platforms in either audio or video format.

You can find songs from the interface itself in your browser and download what you want with just a click. The songs aren't hosted on servers, so everything comes directly from the Internet.

Thanks to MelodyQuest, you can save all the songs you want to your hard drive to listen to them anytime and store them on any device you want.

The application also includes several audio and video formats (MP3, M4A, MP4, WMA, AAC, and WAV), so you can download your music and videos with an extension that's compatible with your device.

MelodyQuest is great for anyone with an iPhone, iPad, or iPod, as it syncs the devices and automatically adds the songs to iTunes.
