As you work on improving your composing skills (and I am deliberately using that term), start seriously trying to work Verse and Chorus structure into your songs, even if you don't have lyrics. A pattern or two (8 bars for the most part, but your genre might vary) of "verse," where you do your wild stuff, and then a return to a pattern or two that is repetition helps to really cement the song in the mind of your listener.
I've written my own DJ software, part of what it does is mark the tracks up for intro, verse, chorus, bridge/drop, "tags" (i.e. just musical bits that are neither verse nor chorus), etc., etc., etc. In the styles I work in, it's the tracks that have verses and choruses that the crowd really reacts best to. Tracks that don't have such a structure tend to be just one long build... they do OK, don't get me wrong, but they don't have the same memorability.
That's not necessarily important for all genres, trance is all about the build (though even trance can benefit from this)... but it is certainly something to experiment with.
Variety, then Reptition, then Variety, then Reptition... lather, rinse, repeat... throw a few bridges in there, an intro and an ending, and you got a song that will burrow into people's ears and lay eggs for later.
