Would anyone be interested in a game where you predict the chart position of as many songs as you like in any country I can get data for and climb a leaderboard?

I hope this post is allowed here. I have an idea for a site that lets you predict the peak position of new songs and climb a leaderboard every time you're right. I've seen the Billboard Hot 100 Challenge exists but it seems to only let you predict one song a day and there's no site for the UK or other countries. Would you play it and what features would you want?
