With iTunes now the third-largest music retailer in the country and the "big box" stores selling nearly two-thirds of all new CDs, things are getting weird, with more exclusive releases snuggling up with previously unlikely bedfellows. Starbucks and Universal Music have announced an upcoming album of Sonic Youth covers entitled Hits Are for Squares, with contributions by actress Chloe Sevigny, Pearl Jam's Eddie Vedder and comedian David Cross. In even more disturbing news, Billy Corgan is forcing fans of Smashing Pumpkins to purchase three slightly different versions of the upcoming Zeitgeist CD if they want all the bonus tracks that close out the disc. With the standard version featuring 12 tracks, does the search for the special rarities head you toward a hip, independent retailer? Unfortunately not, as fans are instead aimed towards iTunes, Best Buy, and Target for "Stellar," "Death From Above," and the title track. One more reason to jump for the iTunes set on pre-sale is a bonus pack of five Pumpkins songs covered by Panic At the Disco, The Bravery, +44, Test Your Reflex, and The Academy Is. Look for the various configurations of CDs and LP vinyls to sport different color combinations on their sleeves.
