"I never know Severus," Q tells him. It occurs to him that he really has no idea what sort of music he might like. He looks up when the doorbell rings. He watches as Severus brings in the package. "Oh, you got one too!" Q eyes it, warily curious and, remembering the sequence of events, nearly jumps off the sofa. He makes himself scarce whilst Severus pokes and prods the parcel, not wanting to interfere, but also not wanting anything untoward to happen to him, just in case.
