If you like watching music videos, you'll love the Windows 8 Vevo app. Vevo's eye-catching design works superbly with touchscreen devices, and, more important, the service streams live concerts and more than 75,000 high-definition music videos.
Don't feel like sifting through the masses of music? Vevo also offers personalized playlist capabilities and "Vevo TV," which is basically a digital version of a broadcast music channel. A sea of content is available in this app—all available for free-as-in-beer free.
