I wouldn't worry about what other people are posting on SoundClick. If everything sounds the same, there's a better chance that your music will stand out. Maybe you could answer this question: how do tracks get ranked? I've posted some instrumentals on soundclick and some have reached #4 in Hip-Hop, or # 200 in Pop, etc. But how are these ranked? The track that reached #4 in Hip-Hop was ranked out of about 60,000 tracks, but in all honesty, it wasn't THAT great of a track. The ranking system seems like a fluke.
