While consumer caution may cause a dip in electronic sales this holiday
season, Apple wrapped up its fiscal year with a 34% jump in
music-related products and services sales.

According to a recent 10-K filing
outlining its fiscal year results, sales for music products and
services jumped from $2.5 billion in 2007 to $3.34 billion this year.
This includes iTunes downloads, App Store sales and all iPod devices
and accessories.

Music sales counted towards 10% of all Apple sales for the year.
