Well, what I normally do is I go to the music store (not the one which sells licenced music, but pirated) and buy the so-called theme compilations CDs with mp3s- trance, house, jungle, progressive, techno, etc. Each CD would include 4-7 previously released albums, mostly compilations and some 150+ songs. Then I would listen to them all and copy the ones that I like.
I also have 56K and becomes a pain to download songs, buying mp3 CDs saves a lot of time and effort.
If you don't have pirated CDs in Croatia (there's where I think you live), then you shoud go to the store and buy the most recent "Dream Dance" compilation by Sony Music. A new compilation comes out every 4-5 months and it has the BEST trance music released. It is 2 CDs with 20 tunes on each- so that's 40 songs, all of which are usually great.
Then you go to www.exactaudiocopy.com, download the latest version of that program, install it, and rip all your tunes into MP3 . ExactAudioCopy is one of the best programs for ripping, created by one German student.
Trance music is beautiful, I can listen to it 24/7
