Instructions for
user:

Choose 10 songs you like and put them on your portable MP3
player.

Notes :

We'll ask the users what music they're interested in and how
they'd search/browse to find it. Our prototype probably doesn't
have exactly what they'd want, so at that point we'll have them
pick something they recognize.

If the users get "no search results," do they understand the
possible causes?

The first track they select will be downloadable to device, but
the second track they pick will not be (to see whether they
understand why).

We won't actually have them download 10 tracks—after the
second successful download we'll ask them if they'd use this
same process if they were downloading 10.

Do not explicitly ask the users about the playlist at this point;
the next task is intended to encourage them to discover it

Do they realize why some music isn't available (because of
legal restrictions)?
