I just listened to the cd of music I’ve so far only listened to through streaming

Oh my god, the quality jump was insane! The album was Everybody Scream by Florence + the Machine, it took me some time to get my hands on my cd so I had to listen to it online first. I knew the quality would be better in some way, but I wasn’t expecting to hear it from literally the first note played! I didn’t even know my car speakers could sound like that. Rip my future wallet because this means I’m gonna have to start investing way more in physical music. Does anyone know how iTunes music compares to cd’s? Because now I’m looking at my entire backlog of music on my phone that I’ve had and listened to for a decade+ and wondering if I’ve been missing out the whole time
