In the early pop music was everything. Back then Christina was Dirrty and Britney was Toxic. Throw it back with this playlist including everything from Outkast's 2004 smash hit Hey Ya to J-Lo classic jam, Jenny From the Block.
When lying in bed and caught on an endless train of thoughts, music is the best remedy to put you out. Drown out the day's stresses and let the playlist do its job — it's built for total relaxation and instant KO.
