<h5>Welcome to Sing It Forward App!</h5>

<p style="text-align: justify;">
Get ready to test your singing skills and memory! First, listen carefully to the first part of the song, then it’s your turn to shine.
Record yourself singing the next 15 seconds on your own, matching the lyrics and rhythm perfectly. Think you’ve got what it takes to keep the music going?
Let’s see if you can hit the right notes and showcase your talent! Unleash your inner star and take the challenge!
