Spotify options:
Unlimited$4.99 / month
or
Premium$9.99 / month

I see nothing free about it.

use the standard service. don't get unlimited or premium.

It mentions nothing about a standard service.

Just go to their website and click "Get Spotify". Log on with your Facebook account, download the installer and you're ready. No payment required. Or if you scroll down on their front page, you see three options: Free, Unlimited and Premium.

Only 4 hours of music a month... No thanks.

Where does it even mention that? The only restriction I could see on the free service was that you had to have ads usually after every third or fourth track. This bugged me so I bought a subscription. I never saw anythign about a limit of four hours a month; wouldn't make sense at all.

I dont think it's worth $5 just to get rid of the ads but at the same time $5 isn't so bad. I have spotify and I don't mind the ads but if you really can stand it I think you should get it.

Where does it say so? I used free for a while, and I could use as much as 10 hours a week.

I saw that doing a search. Seem not to be able to find that now.

When was that? They have changed their page quite recently.
Btw, here's their FAQ page (for the US). You can use Spotify Free as much as you want there. Other countries have different limits, though (7th question on the UK page).
