I need a app to download music?

I'm going on a trip tomorrow & don't wanna be bored. What's a good free app to use? I can't use my computer cause it's broke. Please Help Thanks(: p.s. For my IPhone

ITunes stupid

Go on itunes and type in something like mp3 downloader… There should be a few apps that show up… One of them is this though… MP3 Songs Downloader Free << that is an app that will work and its on itunes:)
