You're probably looking for some background music for a video, like I did, and finding music isn't that easy. Simply follow these steps in SoundCloud to find commercially usable music.

1. Firstly, search up a genre of music you like in the search bar, you can always change this later

2. Now, on the right hand side you should see "Tracks", click on that

3. The "Filter results" tab should now pop up below, under it you should see "To listen to", click on that

4. Lastly, from the drop down menu, choose the category of what you will do with the track

5. And that's about it, not all of the tracks will have the download option and you may have to ask the owner for the track.

NOTE: It's always good to ask the owner of the track before using it since they may not want it to be used without permission, also always give full credits of the track to the owner if you are publishing a video anywhere

Hope this Helps!
