I still many Blu-rays/DVDs and CDs on my collection.

CDs have sentimental value because they offer a tangible connection to music that digital formats lack, evoking nostalgia through physical ownership, accompanying artwork, and personal memories.

The act of holding a CD, reading the liner notes, and having a physical collection links the music to specific moments, events, and personal history, creating a deeper emotional and nostalgic connection than streaming alone provides.

Tangible connection and physical ownership
Physical object: A CD is a physical item that can be held, displayed, and collected, providing a sense of ownership that streaming can't replicate.

Collecting: Collecting CDs, especially limited or signed editions, adds a layer of value and a sense of personal achievement beyond just listening to the music.

Visual appeal: The cover art and folded-out booklets can be a significant part of the experience, offering larger, more detailed artwork than a phone screen.
