Being from South Beach, I can probably help you with this.
Electronic music is a massive genre with all kinds of variety. Just about anyone can find something they like in it, but it takes some searching. Trance has gotten kinda stale, but house (funky, progressive, bangin', downtempo, and many other subgenres of it) is big now... and stuff like dubstep is growing (and amazing)...
Here is a mix I have on my shell account (don't worry, it's free for download, so, no laws broken here):
Gabriel & Dresden - Organized Nature 2007-11-02
Mixes are the way to go (mix cds, downloaded mixes from the 'net, etc.)... because the way the DJ builds the mix is a big part of the impact in electronic music. Increasing intensity, track selection, playing with levels, peaking. A lot of DJs have radio shows for download, also check out houseaddict.com ... I get a lot of mixes from there.
Mixes are the way to go, tracks alone don't do electronic music any justice, but I attached some samples anyways since I had some stuff saved in my YouTube directy. I've seen just about every one of these guys live, house music is something that needs to be played LOUD and POWERFULLY.
