I like Shellshock, but only the Pretty in Pink version for some reason. The mix is less annoying then the 12" in my opinion, which seems to repeat the chorus too many times. I think that's what it is... I like the music, but the lyrics get kind of boring.
As for Sub-Culture, I love the Low-Life version. One of my favorite tunes to walk home to after work. The 12" is horrid. The back up singer needs to be removed, and Barney's vocals need alot of work, he sounds like he is trying to sing with a deeper voice and with soul. I perfer his detached girly voice better on the Low-Life version.
For those who like the Low-Life version, keep an eye out for the "Exclusive Remix" version, it's really great. It has the same vocals from Low-Life but with different music. My only complaint is that it fades out in the end. I found it off the "Out of Order" bootleg.
