Since iTunes Plus launched with cautious fanfare in late May, things have been relatively quiet on the Plus front. The service, which mainly featured EMI's stacked catalogue (sans Beatles and Radiohead), offers higher-quality, DRM-free MP3s at a greater cost than the normal iTunes store. That has changed: As of today, Apple lowered the price on DRM-free tracks from $1.29 to $0.99. Price-cutting isn't the only news over on the Plus side: the service will also add more independent labels to their roster of DRM-free tracks. iTunes' latest moves are likely a response to the prices on Amazon.com's digital music service, which offers DRM-free tracks for $.89 to $.99.
