Streaming tunes inside my head

This is more a request for advice than a contribution. I'm constantly distracted by the buzzing of all sorts of tunes inside my head: “I just wanna feel/real love feel the home that I live in/ cos I got too much life/ running through my veins/ going to waste”. This was this morning's song and even though I like(d) it I now find it annoying; it gets worse when the tune is unpleasant. I've somewhere read a suggestion to write down distracting thoughts as a way to "flush them out" of your head but what do you do when the tunes come streaming into you one after the other? You can't write them down all, can you? Otherwise you would end up memorizing them and condemning yourself to humming them permanently. I know, I score above average on ADHD but it still is manageable, plus I don't have time to follow any special training, let alone going with a shrink (you would definitely need to be very wealthy for that in London).

Ok, it's 8:23 GT, I've been up for 1:30 hours already and haven't moved a finger to get the diss going.
