Several new artists have been added to the iTunes Festival 2013 lineup, including Kings of Leon and Paramore, Apple announced today.

The new additions to the lineup will join big names such as Justin Timberlake and Jessie J at the festival in September, which will take place at the Roundhouse venue in London's Chalk Farm.

The current official iTunes Festival 2013 lineup is now as follows:

Bahamas
Jack Johnson
Jake Bugg
Jessie J
Justin Timberlake
Kings of Leon
Ludovico Einaudi
Paramore
Phoenix
Primal Scream
Queens of the Stone Age
Rizzle Kicks
Sigur Rós
Thirty Seconds to Mars
Vampire Weekend

That's just half of the lineup, as the iTunes Festival will span 30 nights in September. Apple says that it will be announcing the rest of the acts "in the coming months".

The yearly iTunes Festival has been running since 2007, and has in the past featured big-name acts including Amy Winehouse, Adele, Coldplay, Oasis, Paul Simon and Sir Paul McCartney.

You can apply for free tickets to the event via the iTunes Festival app. If you aren't one of the lucky few that manage to get their hands on a ticket (we've heard that there are around 1,700 tickets up for grabs for each night), Apple will be streaming the festival live through the app. Plus, you'll be able to view the festival online afterwards for a limited time.

If your favourite artist isn't yet in the lineup, don't despair. In an email sent out today, Apple wrote: "Who do you want to see play at the iTunes Festival? Let us know on Twitter with #iTunesFestival."
