For music enthusiasts who have an extensive iTunes library, scrolling to the top of your Songs list may be a tedious process. (The problems we have to worry about these days.) But quite honestly, for iPhone users who have more than 10,000 songs stored, getting from ZZ Top to ABBA can require too many thumb thrusts. There’s an easier way to rocket up a long list: Tap the clock at the top of the screen. It'll automatically send you to the beginning. One click is all it takes. The trick works for contacts, e-mail, and websites as well.
