People who are good with audio stuff and songs.. I need help

Many audio editing programs have a "remove vocal" function. However, the results tend to be sketchy at best - there's still some vague traces of the vocal, and the music ends up sounding rather strange during that period (due to various frequencies being removed). Unless the song has an instrumental part that you can loop, your best bet is to find an instrumental version online.

There is no easy way of removing vocals from a recording.

If you have a good stereo recording, and if the vocals remain in the middle the whole time with music all around, then sometimes inverting one channel then mixing down to mono will work reasonably well (audio editing software such as Audacity should do that). It tends to lose a lot of the bass too though. That track has a lot of bass, prominent vocals and not much other backing music so I don't think this technique will work very well there.
