One of the less known offerings by Apple is the "email an Apple music gift card" option. It is indeed surprising why Apple hasn't pushed this harder and the fact that it is hidden neatly at the bottom of one of their web pages within Apple Music is even more intriguing.
In line with Apple Music's theme of no commitment, you can buy a 3-month or 12-month membership and email the membership that to a friend - or yourself. Of course, this gift is used to redeem 40 million songs, custom recommendations and not to mention the creation of playlist and access to curated radio stations.
So if you are running out of ideas why not consider this option from Apple Music.
