I'd find it hard to believe anyone is "deeply in love" with a news piece. I'd be a bit worried if they were.
The legal world is a broad spectrum that covers a range of topics or matters. You just have to find the topics that you naturally gravitate to - you are never going to be able to read everything even within a niche of law, so this is just a case of finding the things you are more interested in and so you choose over all the other topics you could potentially be drawn to.
If its the Astroworld example, then you then to think carefully about the link to the firm. Do they work on these matters/with their clients? How could the story impact the firm or their clients? There needs to be some form of connection for it to be relevant to your application. Why is the topic relevant to you and to the firm? This is the part most candidates completely forget about - they just choose something to try and impress, but they aren't really thinking about the relevance to the broader document or conversation.
If you are really struggling, then it sounds really brutal, but you have to question whether this is the right career for you. And I come from that as someone who is not interested in these topics at all. Even if you can fake your interest in an application or interview, you are going to have a pretty miserable career feigning this interest for the next 40 years.
