How about buying her a Coldplay album or merchandise, such as a t-shirt, hoodie or poster featuring the band? You could also consider getting her tickets to a Coldplay concert, or arranging a Coldplay-themed weekend for the two of you, perhaps by visiting a city where the band has performed or visiting a venue where they have played in the past. Additionally, you could create a personalized playlist of Coldplay songs that are special to your girlfriend, and include some of your own favorite tracks as well. Finally, if you are feeling crafty, you could consider making a Coldplay-inspired gift yourself, such as a painting or collage featuring lyrics or album art.
Or you can get her a star map with an important date you share.
