Q: Here’s a simple question, but an important one for me, that I haven’t seen explicitly answered anywhere yet:
When I put a song in more than one playlist, does it take up another copy’s worth of hard drive space? I had a primitive MP3 player before my iPod, and it did.
A: Absolutely not.
For the iPod (and, of course, iTunes), playlists are simply collections of shortcuts to songs which exist in only one place – the Library. This makes playlists an entirely “free” and fun way to expand and enhance your listening habits.
