Popular UK online music shop 7digital this morning launched its US store. The primarily web-based service focuses on price and is offering some newer albums as well as many older ones at $7.77. Songs can also run as low as 77 cents each, and all downloads are platform-independent, 320Kbps MP3s that should work with Apple devices as well as most other portable players. The store has long had access to all four major music labels as well as key independents.
