You could build a very long wish list from a mansion tour. Carmelo Anthony's music room makes a good argument for choosing one room and getting it exactly right.
Architectural Digest's Westchester feature describes a space with a pink baby grand piano, a record player, art and a fireplace. Anthony worked with designer Cassandre Bonhomme on the home. Elsewhere, a bedroom became a shoe closet, while a separate mindfulness room offered a place to meditate. Read the original feature.
The music room is the one I would bookmark. A piano can become an expensive object nobody touches; records can end up stacked in a corner. The appealing idea here is giving listening enough space that it becomes the reason to sit down. Put an album on and let the room earn its keep.
There is a practical version of that wish for an ordinary home. Start with the chair you actually enjoy sitting in. Put the music within reach. Hang something you chose because you like looking at it. Resist filling every remaining surface just because it is empty.
Watch Anthony's official AD tour as an archived look at the Westchester home. The shoe room will have its fans, but give me an uninterrupted hour with a record and that pink piano in view.
