How about a karaoke set? It could be a great way for your friend to practice their singing skills and have fun at the same time. You could also get them a subscription to a singing class or workshop, or tickets to attend a concert or musical event. Another thoughtful gift could be a personalized microphone or songbook with their favorite songs.
Or you can get her/him a star map with an important date you share.
