Hmmm. I've been in the trap scene myself lately, and this is the trend I see. Soundcloud just works so much better because of the community, the ease of linking artists together (I love how rappers will feature other rappers, then you can go listen to that other rapper and explore an entire new world of music), the overall presentation of audio with waves, similar to an audio player (Google tries to do this more with Google Play Music rather than Youtube). Souncloud is just a much more polished experience for music.
