Not Quite, Actually

“Unless you’ve got money to burn, paying 99¢ or more per tune can add up."

Whether or not you've got money to burn, 99¢/song "adds up", the only difference being in how you perceive it.

Also, spending "$3 or $4 for coffee—over and over, day after day" is nothing but a brutally callous and disgustingly flagrant waste of money, and it's a fucking shame we tolerate it at all, or even consider it within the realm of normal behavior. You're addicted to caffeine? Fine -- get that shit pure, like the slimy drug-addled crack baby you are. Or if you like the taste, take it straight -- real straight.
