Music quiz games are fun.
But why limit to 1 a day? They're going for Wordle-style "cultural trendiness", maybe hoping to draw people to Spotify if a daily Heardle trends on Twitter.
Not gonna happen. Wordle was a flash in the pan. It's already dying.[0][1][2][3] And I doubt a "mee too" product will go as viral.
Spotify bought Heardle, kicked a few countries out that could previously play, and now can't, and took away people's stats. Heardle isn't trending on Twitter, and the Spotify subreddit literally isn't talking about it.

https://www.similarweb.com/website/wordle.com/#overview (they abandoned that domain name, switched to nytimes.com months ago)
It's not credible to spend (presumably) millions on this, when they're struggling to roll out Hi-Fi (7+ months overdue), their share price is down 73% from ATH, and YouTube Music and Amazon Music are gaining ground.
Spotify's CEO announced last month to investors that subscription price increases "are part of the strategy", though they're unlikely to do it in the next few months since they saw how it backfired for Netflix. Why not focus more on core service/social features, not gimmicks?
