What music app is free without Wi-Fi connection?

Ok so when I travel I always listen to same songs on my music library because I have an iPhone and pandora doesn't work on Canada cuz I live in Canada so I was wondering is there a radio app or music app you can use anytime and anywhere without connecting it to Wi-Fi and is for free?

V/D also known as this app called video downloader it's free.
