About a decade ago - on Idea - Andy asked me about doing library music. I sent him a long PM recounting my own experiences (good and profitable) and suggested he go with the biggest name possible. Not that he listened to me, but it doesn't GET much bigger than Warner/Chappell.
This will hopefully not only see work he has already done used in movies, television and video games, but open avenues to doing new work - and even newer collaborations with others. And of course new (and more) money.
ASCAP and BMI and SESAC. BIG money. Not that piddling "a million downloads for a hundred bucks" bullshit.
