Hi! Your brief is a very clear one, thanks for that.
I have a large library of 60's to 90's songs of CD quality, so I can easily tap into that rather than having to download low-quality tracks. Mixing the tracks is an easy task, as I'm used to creating medleys for purposes like Zumba workouts and even speeding tracks up for Samba dances. Other than mixing the tracks seamlessly, I'm also able to match the tempos of all tracks in a mix so the workout flow isn't interrupted. May even finish in a day, rather than 2.
Do feel free to contact me if you would like to discuss more :)
Thanks for reading this! Have a great day ahead!
