Can you put non-iTunes music on iPods/iPhones?

I'm gonna get an iPod or an iPhone soon, but I'm wondering about music.
On my phone, what I do is I download music online for free on my computer, then I connect my phone to the computer and copy/paste onto my phone.
Can you do that with iPods/iPhones, or can you only buy music from iTunes and put it on there?
And when you connect it to your computer, can you go into the iPod/iPhone so you can copy/paste stuff from and onto your device?

You can but you'll have to create a folder of all your music and export it to the iTunes library then sync it to your iPod/iPhone.

Of course you can, I have never bought any song in itunes (have bought some books, but never songs) and I have a ton of mp3 songs on my ipod / iphone. Just convert any old CD to mp3 format (windows has this feature on it already), or take any other mp3s and just select and add into itunes, then sync to your phone.

  • Would music I buy from the iTunes store go on non iPhones? So I currently have an iPhone 4, I've had it for about three years now and it's not working nearly as well as it used to so I'm interested in buying a new phone. The Sony Xperia Z. However I spent a lot of money on music from iTunes. Will I be able to listen to all that music on the Xperia Z?
  • Why do people with iphones also have ipods? A lot of people I know have iphones. But they also have ipod touches. Why? If you have an iphone (which is the exact same thing as an ipod touch plus calling capability) where is the need for an ipod touch? Just doesn't make sense to me.
  • Why do people put passcodes on their iPods or iPhones? My girlfriend has an iPod touch and my friends daughter has an iPhone and they put passcodes on them. I have an iPhone and I don't need one on mine. My friends daughter has a little brother and I understand that's why she has it on hers but my girlfriend doesn't have any brothers or sisters so there's so reason for her to have it on her iPod. I don't get why they put them on there. Why do they have passcodes on their iPods and iPhone?
  • Why do people put passcodes on their iPods and iPhones? My boyfriend has the iPhone 5 and he has a passcode on it. I have an iPod touch and I put a passcode on it I don't really have much on there but I just did it because he did. I know his password but he doesn't care. He lets me use it sometimes. Why does he have a passcode on it?
