well, it's hard to give any feedback from the previews, specially from Martin_rc4test3_2.mp3 which in my ears did sound most promesing. but it ends just when it's getting exciting? I would like the drums that 1:04 to be more powerfull, more punchy and outstanding if you know what I mean. The beat is nice. nice flow and rythm and I like the atomsphere, and the bass. the crashes sounds a bit harsh and the ride doesn't really sound that real. well. the filtered beat fits well into the song. that's my opinion of the song, hard to say more now since it's as I said before a very short clip that ends as soon as it gets interesting, would like to hear more!
