SoundLine is a simple visual explorer for SoundCloud songs. Start by typing a song or category you are interested in, then keep clicking song titles that interest you to build your "line". You can also change midway so go crazy.
The idea behind SoundLine arose from the want to browse SoundCloud songs in a more visual way. It works by getting the "Related Tracks" section of a SoundCloud track and blowing up the images to make it look more attractive.
Unfortunately, SoundCloud does not officially support a related tracks listing in their API (until v2 releases, see credits.txt) and so I had to have a few sneaky workarounds...
When you load a track on SoundCloud's main website, a request to https://api-v2.soundcloud.com/tracks/{{trackid}}/related is send and JSON with a listing of related tracks is returned. Unfortunately, if you try to request the same json from a client side webpage loaded from localhost or your personal server, you will encounter a cross site request error as modern browsers are configured to prevent such requests for security reasons.
Lukily I was able to get around this by adding an additional route to a nodejs server script that I had from class (credit Joe Mertz [email protected]). This route accepts api https urls at /crossrequest?theurl=, does the request on the server side and returns back the json to the client. In addition, I added response headers to that route so that the server itself will allow cross site requests.
For anyone else interested in doing this, I advise you wait till SoundCloud releases it publically in their api so that we do not cause any disruption to their server load :3
Here is how it looks. If you're lucky the page is still up here.
