If you have a smartphone (and you most probably do), chances are you have it filled with pictures, videos and tons of different apps which means you don't have much storage left on it. Music files, despite not being particularly big, can take up a lot of space on your phone. If you want to make sure you can always take your favourite music around with you without having to stress out over how much storage it's taking up on your smartphone, buying an iPod Touch is a great idea because some models come with up to 128GB of storage which is way more than enough for thousands of songs.
