im kinda n00b trance lover but ive come across these songs that rock but r not well known, i'll list them here i think u can only find them on kazaa/kazaalite (ill also list the lengths of those with diff versions etc, make sure u get the right mix aswell):

silvertear - so deep (perfect sphere remix) 6:32
(fifa world cup anthem) - vengalis (tokiyu ishono remix, or somethin like that)
neon genesis evangelion - space dreams eva
anastasia - join me (no, not the blonde artist)

also this ones popish but its ok for those who can stretch their taste
kosaka riyu - true (around 4:00 length)
