Reply to Track Selection

I have been experimenting with DJ'ing since Dec of 2010. I have a really successful mix on SoundCloud.com/djquant. I am working on a new mix, and as always, I have a difficult time really finding the perfect tracks to mix. I have search for threads regarding this topic (along with the web) and really haven't found the answers I am looking for.

If some people could check me out on soundcloud and give my mixes a listen and provide some feedback on them to tell me how I am doing in general. I would appreciate it. Aside from that if some people can chime in on how they select their tracks and how I can do a better job on finding tracks for my mixes I would greatly appreciate it! This is one area I really struggle in and advice is much needed!

Thanks!
