TuneWallet...Has three- tier song pricing complicated your iTunes experience? Then change the tune, with TuneWallet. One click, and this freeware adds $1.29, .99, or .69 to a prominent display of your running total. Another click subtracts a song's price. And the design -- translucent, clean, intuitive, and small -- means that your focus stays where it counts: on those tunes. TuneWallet. Sounds good.
