Still Standing has potential to be a radio BANGER! I'd like to hear bigger drum sounds. A more noticable change in the beat would be nice too; playing a lead in the hook may help.
So Soulful and Talk To You are OFFICIAL. Love the way you chopped Talk To You. A better mix would set these beats off right. Also, to keep the beats from sounding so repetitive you can play other instruments underneath the sample (and this is just a personal preferrence), but it allows you to do more with the beat.
You Got is probably my favorite. I've chopped and sampled this song also, and I can admit that yours is better.
Overall I'm diggin the sample joints. The original tracks have a few minor pitch issues and need more instruments for my personal taste. But I see yall will make alot of noise with the beats.
