Wellllll.... I don't pay for mine *cough* so if you're ok with that... I copy the URL from a YouTube video w the audio I want, and go to hdtransform to download it. I downloaded MP3dit to rename the downloaded songs I get. Hdtransform doesn't have an app yet, so I go to their site. Yes, I do all this on my phone, no computer needed. I also noticed hdtransform took awhile to load on the stock browser, but loads great on the Opera Mini browser (if you don't have this browser, get it now, it's fast!) But it's FASTER to download songs to your phone using a computer, so I wouldn't recommend this if you're downloading a bunch all at once.
