For all the DJs! @DjCity is the best...

www.djcity.com

I am a huge supporter of this website DjCity. It has everything a DJ needs for the radio, clubs, mixtapes, or even to make remixes. It has all the popular genres that you are looking for, even remixes made by other DJs of many of the popular songs fans like. I think I've been a member for the passed 3 years. Very reliable source for any DJ. For example, do you know any songs that you're trying to get but can't find a free HQ download of it? They most likely have it and EVERY version of it plus the remixes.
