I built this for my daughter and I for practicing guitar, it's easier to string together clips from concerts/music videos and trimming the start and end and play all together, especially grabbing a song or two in the middle of a concert.
Lots of other potential uses, but that was my motivation.
I did a double take on the domain name, it's very similar to mine https://chiptune.app :)
Good idea of putting musical samples back-to-back, thanks for checking it out.
