Lou Reed’s death this weekend has affected many people—from Velvet Underground fans to Reed’s bandmates to countless musicians and artists from all over. After the news spread of Reed’s unfortunate passing, Twitter and Facebook exploded with countless sentiments of grief as people mourned the great rocker’s death. Here are some of the responses that have been posted:

“The world has lost a fine songwriter and poet…I’ve lost my ‘schoolyard buddy.’”

-John Cale via Facebook

“The news I feared the most pales in comparison to the lump in my throat and the hollow in my stomach. Two kids have a chance meeting, and 47 years later, we fight and love the same way—losing either one is incomprehensible. No replacement value, no digital or virtual fill…broken now, for all time. Unlike so many with similar stories, we have the best of our fury laid out on vinyl for the world to catch a glimpse. The laughs we shared just a few weeks ago will forever remind me of all that was good between us.”
