How about gifting her a DJ course, so she can learn how to mix electronic/dance music and maybe even create her own tracks? Alternatively, tickets to an electronic/dance concert or music festival could be a fun and memorable experience for both of you to enjoy together. You could also surprise her with a new set of wireless headphones, perfect for listening to her favorite electronic beats while on the go. If she's a vinyl collector, consider getting her a turntable so she can play her favorite electronic/dance records at home.
Or you can get her a star map with the date of your anniversary.
