captain amazing if you were in reach i’d wallop you for linking to that first song- it’s gonna bore into my brain and be killing me at 6am, i can tell. i’m letting you off because of the redeeming quality of the second one though. 
the music thing does work. just not with ska tetris on trumpets. i used to use this kinda thing (bear with it, the first 1:30 ish isn’t the helpful bit). http://www.youtube.com/watch?v=cDGPkTaKQbY
…. just enough to keep the fidgetty ADHD part of my brain busy so the rest can do its thing.
