Better SoundCloud (BSC) allows you to filter the content you see on the SoundCloud website in a myriad of ways to more easily find tracks and content that interests you. BSC is also the only extension that allows users to filter tracks by their duration, in addition to many other factors.
The values which you may filter out content include the following:
- Minimum Song Duration
- Maximum Song Duration
- All Playlists
- All Reposts
- Promoted Posts
- Main Stream or All Profile Pages
- Reposts from specific users
Furthermore, you can also choose to not remove content entirely, but rather just collapse the item into a single line of text in case you want to view it without changing the filter settings ('Remove Filtered Posts' option).
This project is actively maintained and open source. You can find the Git repository here to submit bug reports and view/modify the source code: https://github.com/brocef/BetterSoundCloud
