"Many songs you listen to contain so much nonsense that we belive you deserve the option of skipping all the junk. For example, take the first 14 seconds of popular rapper Jay-Z’s song called Threat. How about the end of this same song. It will make sense if you could skip all this nonsense and just listen to the real song. With SkipTheBS you can.
