u can download Mp3Rocket for free. It has a YouTube mp3 converter, so u can convert the audio from a YouTube video to an mp3 to your computer. And it has FM radio too! :D
Go to www.wuzam.com and type in the name of the song u want to download and the name of the singer/band who does it. It will give u a lot of download options, but be careful cuz not all of them work. :)
