Companies join to push music on memory cards

NEW YORK (AP) — Just as vinyl once gave way to compact discs as the main physical medium for music, could CDs be replaced now by a fingernail-sized memory card?

Perhaps not entirely, but SanDisk Corp., four major record labels and retailers Best Buy Co. and Wal-Mart Stores Inc. are hoping that albums sold on microSD memory cards will at least provide an additional stream of sales. The companies were expected to unveil plans today to sell memory cards loaded with music in the MP3 format, free of copy protections.

Called “slotMusic,” the new format is meant to address two intertwined trends. Most albums are still sold in a physical format — 449 million were sold on CDs in 2007, while 50 million were sold digitally, according to Nielsen SoundScan — yet CDs are decreasingly popular. Albums sold on CD dropped almost 19 percent last year.

Given this, the record labels — Vivendi SA’s Universal Music Group, Sony BMG Music Entertainment, Warner Music Group Corp. and EMI Group PLC — are hoping slotMusic can be another physical revenue source — and one that is more versatile than CDs, given the kinds of gadgets people carry around these days.
