YouTube to mp3 apps

[mtmt88]

Is there a YouTube to mp3 app that actually works?
I need it to:
Edit artist and title once converted
Save mp3 file to default (Xbox) music app

"Tube mp3 downloader" works just like this but after using it a few times 2 weeks ago it no longer works.
YouTube apps like "mytube", "YouTube hd", "all tube grabber" only save as videos and not music files.
"Music+" saves files to Xbox music but doesn't grab files from YouTube.

Please help, thanks!
