Eh
It does what its supposed to. It converted a video to audio. Which is cool, theres a song I like but its a tv theme song and as far as I can tell the full version doesnt exist anywhere other than YouTube. Anyways I downloaded the video and got it on my phone (Apple will typically remove any app that allows you to download videos from a streaming site that doesnt support downloads) and converted it to an MP3. The biggest flaw (aside from not being able to change the thumbnail)is that it doesnt import your new song to your music library. I really only wanted this song specifically. The fact that I cant get it into my music library means Ill have to open the app just to listen to one song, which makes this app completely and utterly worthless.
