I have been rocking out to the Yeah Yeah Yeah's during my work-outs recently. I created an awesome 'mix-tape' of their best tracks on Spotify last week. I find having some excellent music can really help get into the zone for some of the harder C2 interval sessions.
I have had a self-imposed ban from the YYY's since my 100k session Easter 2012 because I was unable to change the music without the C2 timer clocking off the monitor. I ended up listening to the same YYY's album on repeat for 9 1/2 hours! Luckily the darker memories of that torturous endurance episode has faded enough for me to listen to their music again without having flash-backs to hand blisters and back ache.
