@Reid-Larson You mean by singing and recording them into a microphone? You probably need to do it yourself or you know a singer. Or do you mean a written form of the lyrics inside the Soundpool loops? A̶s̶ ̶f̶a̶r̶ ̶a̶s̶ ̶I̶ ̶k̶n̶o̶w̶ ̶t̶h̶e̶r̶e̶ ̶a̶r̶e̶ ̶t̶e̶x̶t̶ ̶f̶i̶l̶e̶s̶ ̶w̶i̶t̶h̶ ̶t̶h̶e̶ ̶l̶y̶r̶i̶c̶s̶.̶
Edit: As far as I know there are NO text files with the lyrics.
The Soundpool loops, as I understand it, are created for Magix by third-parties. If you could discover the identity of the creator of the specific loop you wish to know the words of and if you could find a method of contacting him/her you might be able to ask for a copy of the lyrics.
But, whether it is really worth all that work, personally I doubt! 😬
As a musician if no lyrics available I tend to use my headphones and write down lyrics myself, or you could try a free online mp3 to text converter/transcribe.
Have a search on Google.
With these converters it's trial and error for accuracy, some may work, some may not.
