My vote goes to RStrax and Susan.
While i was impressed with some elements of the 1st entry (for example, josh's rapping, which i think has improved), it lacked the quality that the 2nd entry had in terms of polish and finish. A large part of this, i suspect results from a crappy mic, and that's unfortunate. The 2nd entry maintained strength and clarity throughout the song and that's why i'm voting for it.
nice job both entries
