Listened to first link you provided - Right off the bat this kicks into top gear, top notch. Not only outstanding performances (all instruments, vocals), but also very tastefully done. Vocals are powerful, very well suited to this genre.
From about 3:50 the guitar lead/slide work and organ could come up a tad, got really great work happening there. To further explain; When you leave off from the previous guitar work, that's when I notice a drop at about 3:50.

Another top notch song, top notch performances. Those half/timed changes are very cool.
The very first part (intro) and the hand claps are okay - But I would imagine those claps would be cool in a live scene - when crowd comes into play.

Cool slow tempo number, vocal's certainly conveyed the message very well. Again, top notch performances all round. This is a short number? No, that up tempo brass and all kicks into high great, brilliantly done, great send off. Way to go man!
