Most if not all of today's trance music you can find is totally worthless. There are, however, a few older 'goa trance' albums which are worth listening to.
Indoor - Progressive Trance (1995)
Solar Plexus - Images Of The 5th Dimension (1998)
Electric Universe - One Love (1995)
Aeon - Transe Modulaire (1996)
On these, the focus is on making expressive music instead of filling up uninspired songs with movie sound samples and loads of noise.
