Cover art for Cinderblox lyrics by Sonata Arctica

In my opinion it's about alcohol, maybe drugs; personified as woman.

"When you're done with your wining and dining, you make a man do things that wind him up in jail" - Starts off innocently enough then once you're drunk you do something stupid.

"Every wall in here is blue" - A hospital or rehab centre rather than a jail, makes more sense to be rehab as "every man here knows you too", makes more sense they're all patients suffering the same addiction rather than prisoners that all know the same prostitute.

"If I one day find my way back home" - Never tried to find your way home while blind drunk :-p?

"Can I stay away from you, if I get out of here soon" - Addiction.

"Would the road be paved by my mistakes, by the law or by you" - Drink driving causing death and destruction.

"We have seen your every curve" - Bisaphic curve? Blood alcohol curve? Glasses? It's a liquid?

"Sole good purpose you serve" If in relation to the graphs, the sole good purpose is teaching people that alcohol is bad, being rehab and all.
