15. SBTRKT Jamie xx: An impressive showcase for what can be done with electronic performance, SBTRKT offered a set that, at times, captured the true magic of the studio.
14. Ed Sheeran Foy Vance: Our headliner only required a loop pedal and a back catalogue of massive chart hits to succeed. Sheeran was still at his lyrical-gymnastic, guitar thumping best for his iTunes performance.
13. Lenny Kravitz: With a brand new album, a brand new band, and a brand new legion of fans thanks to his performance in the Hunger Games films, Kravitz demonstrated his brand of funk rock just as well as he has for decades.
12. Kylie +MNEK: There are very few artists who are as shamelessly pop, and unavoidably likeable as Kylie. If you surrender yourself to the glorious campness of her live shows, as the iTunes crowd did gladly, then you will have a better time than you thought possible.
11. Elbow Nick Mulvey: It wasn't the kind of night that was ever going to veer too far from the well-trodden path of the Elbow live experience, but for those expecting to hear some of the most life-affirming, anthemic choruses ever written by a British band, they came to the right place.
10. Sam Smith Sohn: There's a reason Sam Smith was named the Sound of 2014, and is that rare British talent that works wonderfully in the United States. His iTunes show displayed that talent with aplomb.
9. Robert Plant Luke Sital-Singh: 46 years after he last placed Camden's Roundhouse. Robert Plant returned. The Led Zep reunion may now never happen but 'Whole Lotta Love' has never sounded better.
8. Kasabian: Is it arrogant or genius to be your own support act? Either way, that's just what Kasabian did during their iTunes slot - playing their debut album in full to open the show, before returning to the stage for a second set. A career-spanning triumph.
7. Placebo The Mirror Trap: Brian Molko and co. returned to their British roots with a hit-laden set - a set that makes it all the more exciting that they're rumoured to be back in the studio.
6. Blondie Chrissie Hynde: Even slightly ropey versions of 'Groove Is In The Heart' and 'Fight For Your Right' somehow work, such is the charisma and status of Blondie, who still triumph after 40 years in the industry.
5. Ben Howard Hozier: Howard established an intense atmosphere which perfectly showcased is more mature, darker sound, but it was opener Hozier who really stole the show, with his soulful, powerhouse vocals.
4. Pharrell Jungle: One of the biggest US artists around at the moment showcasing some of the warmest, catchiest songs at the tail end of the summer, preceded by one of the most exciting new British bands of the moment. What could be better?
3. Jessie Ware Little Dragon: Ware's stunning blend of underground dance appeal, superhero vocals and quiet restrain proved simply unstoppable.
2. Ryan Adams First Aid Kit: Adams liberally cherry-picked from his exhaustive back-catalogue, much to the delight of those who have been tracking his turbulent, 20-year-long career. In support, First Aid Kit, who have been alive for as long as Ryan Adams' career has been going, were incredible.
1. Beck Jenny Lewis: Jenny Lewis's career-spanning set of blissed-out Americana was just the beginning of one of our gigs of the year. Beck's performance covered the entire musical spectrum, and proved that he can incite possibly one of the most explosive responses we have ever witnessed at an iTunes show.
