Use of HIGH quality speakers or earphones is suggested, because trance is about manipulation of frequencies in combination of sub-frequency beats, hence you need a good set to reproduce it, as it was intended to be.
Trance is MUSIC, it's not lyrics... lyrics are said in a musical/synthetic way... and in majority of lengthy trance masterpieces, lyrics are just a few short phrases.
Viva la Trance & grazie to the people producing it by utilizing the full potential of Synths ! Let the music play and feel the energy going into you !
