I remade Turn It Around for you, let me know if you want me to explain how I made any of the sounds. The bass is just a sub (lowpassed trancebass 1 from nexus), electric guitar playing the root and a 5th an octave up, a saw with an envelope on a highpass to make that 303 'wow' sound, and a dephased saw playing the root and the 5th, and finally an picked bass guitar with some distortion :~)
