Ok let's see do I go to Music store A with thousands of albums and artists or Music store B with a lossy media format and hundreds of artists.
You use the popular music store because that is WHERE MUSIC IS AVAILABLE, and frankly on top of that Apple has tons free material from bands and most music is available there weeks before it hits actual cd shops.
People usng LINUX don't need a popular music store because they intend to steal music anyway.
in my old age i've concluded that all Microsoft and Apple users are just stupid sheep... your comments have done nothing to dispell that notion.
