LSD for me, I remember music and can for some reason, remember it so clearly to listen to some songs in my head. The other day, (This is going to sound crazy but I'm not lying) I listened to the Beatles for the first time on acid and it was beautiful. Also listened to system of a down and one band I don't know the name of. On MDMA, sometimes, I can't decide on a song cause I enjoy listening to so many different things whereas with LSD, I can focus a bit better.
