You must sign up for an iTunes store account. To do this without a credit card, it requires a little trick. Open iTunes. Click on iTunes Store. Find a free iPhone app (I chose Google Earth). It is irrelevant whether you have an iPhone. Click the download link. You will be taken to a registration page for an iTunes account. The difference is this time the option "None" is available beside the credit card options. Complete registration, and log in to your account from iTunes. Select all of your music, right click and click "Find album art".
Get itunes XD
If by coverflows you mean the pictures on music albums, then you need to purchase the songs from itunes to get the pictures to view in coverflow.
You are only allowed to get the free songs from iTunes for free.
No its not free
iTunes features a weekly free song which is usually changed every Tuesday. (See links below)
Song prices are determined by the artist and/or record label. The majority of popular songs on the iTunes store are not available free. (Holly's Answer) lol: you can also use frostwire or limewire to download songs to your iTunes library for free
No, but some podcasts are free.
