Hello, I'm an experienced sound designer and composer. I can cut out verses and stitch the song for a smooth transition, switch verses, shorten certain parts, create a shorten version of a song by changing the structure, whatever is technically possible and needed. Please provide more details - what are the songs and how many do you have.
Will alter my bid according to the amount of work you have
I also speak Russian, if that' needed. Get in touch, Leon
