Apple's innovative iTunes music service is still the market leader in music downloads, but after more than a decade of growth, sales of music tracks on iTunes have been declining. Last year saw the largest drop in sales — 14 percent. The drop is attributed to the increasing popularity of streaming music services such as Spotify, Pandora and YouTube. These services give fans access to millions of tracks from any Internet-connected device for a monthly fee or in return for listening to commercials.
