In the years since Hermione had last lived a Muggle lifestyle, their technology had advanced considerably. She remembered having a portable radio player as a child, purple plastic with glitter and stickers, the joy of putting a cassette tape inside and carrying her favourite music around. Nowadays, the music players were unbelievably tiny, and the British Library had shelves upon shelves of CDs that could be made through the computer to play on the tiny machine. She’d purchased for herself a pair of large, high-quality headphones (the price had shocked her, but thankfully, her Ministry paycheck was substantial) and loaded her device with twenty different music albums.
