"Let's start with clarifying question -> What do we want to achieve with increased engagement?
Let's say Spotify has personalization that prefers more engaged songs/podcast to be available to new users (who have not heard that song). Along the same lines as Facebook/Linkedin/Instagram prefers posts. The more the song/podcast is engaged among users, for more people it will be visible to listen.

"BETWEEN and HAVING clauses in SQL serve different purposes:
1. BETWEEN Clause
Used to filter rows based on a range of values.
Works with numeric, date, or text values.
Can be used with WHERE or HAVING clauses.
The range includes both lower and upper bounds.
Example: Filtering employees with salaries between 30,000 and 50,000
`SELECT * FROM Employees
WHERE salary BETWEEN 30000 AND 50000;`
2. HAVING Clause
