Led Zeppelin is no longer "dazed and confused" by the MP3 world. It's capitalizing on a monumental one-night-only reunion by, at long last embracing song downloads — but through Verizon Wireless, not Apple's iTunes. Take it as another sign of the rising unease with Apple's dominance of digital music. The cell-phone carrier will sell full song downloads and ringtones of popular hits. The entire Zeppelin catalog and other partnerships will follow. [NYT]
