Digital singles are convenient, cheap in distribution with potential profit.

Today i was walking and first i was addicted to listening to Sarah Brightman and her epic "fleurs du mal", "running" and "phantom of the opera" so i was set in such mood and then Ayu's "Lelio" started xD Such a style change xD I decided how horribly varied my tastes are! When Lelio started after those songs i imagined Ayu from the music video blowing pink bubble gum and exploding on her face
Actually i decided that this is the only element missing in this video so it could bear the title of the most cheesy video ever from her (not that it doesn't).
