How about a vinyl record player along with some of her favorite alternative/indie rock vinyl records? This way she can enjoy her music in a new and traditional way. If she already has a record player, you can gift her a vinyl subscription where she will receive a new vinyl record every month of her favorite genre. Another idea could be to gift her tickets to a concert of her favorite alternative/indie rock band or artist.
Or you can get her a star map with the date when she was born.
