How about getting your friend a karaoke machine or microphone? This would allow him/her to have karaoke sessions in the comfort of their own home. Alternatively, you could get them a gift card to a karaoke bar, so they can go out and sing with friends. Another idea could be to create a custom karaoke CD or playlist with their favorite songs, or a by a book with sheet music for their favorite songs. Finally, you could get them a wireless karaoke microphone that can be used with a smartphone or tablet. This would allow them to sing along to their favorite songs anywhere they go!
Or you can get her/him a star map with an important date you share.
