Verse 1:
Listen up cause it's time to
Free your mind, take control
Throw away the doubts and be unstoppable
You're the master of your destiny

Must be the music, it's got me feeling groovy
Must be the music, it's hypnotizing me
Must be the music, it's got me feeling high
Must be the music, it's got to be the music
Verse 2:
Everybody dance now
Let your body move
Feel the rhythm, let it control you
You don't need no limits
Chorus:
Must be the music, it's got me feeling groovy
Must be the music, it's hypnotizing me
Must be the music, it's got me feeling high
Must be the music, it's got to be the music

This is not a test, this is pure sensation
Move with the rhythm of the vibration
There's no need to doubt, you're not alone in this
You can do anything with the power of the music

Must be the music, it's got me feeling groovy
Must be the music, it's hypnotizing me
Must be the music, it's got me feeling high
Must be the music, it's got to be the music

Everybody sing along, must be the music
Everybody move along, must be the music
Everybody dance along, must be the music
Must be the music, it's got to be the music.
