YouTube Music Downloader's interface is pretty basic, which goes with the territory: fields for Video URL and Save To (destination folder) as well as the previously mentioned drop-down menu, which changes its options between audio and video formats when you check either MP3/Music or Video. A Status bar tracks the job; a check box tells the program to delete videos after conversion. A Skin button has Hue and Saturation sliders that can produce any interface color you'd like. Clicking Update informed us that ours was the program's latest version. That's all there is to YouTube Music Downloader's controls, except a Help button that accesses basic Web resources.
We browsed to YouTube, searched for a familiar tune, and copied its link from the search results. We pasted the URL into YouTube Music Downloader, selected our format (which depends on availability), and pressed Download and Convert (actually, "Download and Convert!" but we kept our powder dry until the results were in). The job completed in a few seconds. YouTube Music Downloader not only grabbed the tune but the cover art as well. The results more than earned the exclamation mark!
