You get 40 hours a month for free according to their site, and a full commercial free unlimited time subscription is $34 a month. With this you also get 6 song skips per hour, but that's every hour as opposed to a maximum of 12 per day with the free service, and no banner ads.
If you can deal with the commercials and less skips, when you run out of the free 40 hours you can subscribe for the rest of the month for $1. Pretty good deal I think.
I have yet to hear a commercial in probably 10 hours
My wife says she's heard about 3 but she listens all day.
