Whether you are a Mac or a PC, an iPod or an MP3, sign up to Apple's prize draw and you could get free tickets to the iTunes Festival between 1st-30th September.
Every year Apple hold a month long concert series at the Grade II listed Roundhouse building in Chalk Farm. Tickets are given out by ballot, which you can apply for at the iTunes store. Considering concerts like this can cost to an excess of £100, this is a great opportunity to see and hear world class artists without spending a penny (although toilet facilities are available if needed).
There is no guarantee you'll win, but those lucky few who get picked out of the iHat don't need to worry about being drafted to a gig they don't want to see. Each night has a separate ballot, with different star singers, and you can choose which ones to apply for. Not all the guests have been announced yet, but a sneak preview of who you can expect to see include Justin Timberlake, Jessie J., Primal Scream, Phoenix, and Kings of Leon.
If you are not lucky enough to get picked, you will also be able to watch the gigs on iTunes online.
