I checked several of the ’14-websites’ links in the article from yesterday. The ones I’ve checked all have some frustrations to their interfaces, such as also trying to sell you not-really-free music, or lackluster filtering capabilities, or giving you choices for filtering that quickly lead to a ‘no-results’ page.

Then you have to listen to the individual tracks and see what moves you and is suitable for the mood of the words and imagery that you’re conveying, and what doesn’t.

A long process. But … I mostly like what I see at CCTrax, and here is at least one example of liking what I hear there too.

Here’s another, useful if I ever sleep by the beach.

kopoc (Label) says: a heartful dub-techno work (soundtrack). While creating this music, I was greatly influenced by my trips to the sea. I wish you were immersed into the atmosphere of traveling alongside the endless ocean. Just enjoy it!

Now I know. Now you know.
