i am rather surprised how positive all the comments these songs have received are. i might have higher standards than other people who have posted in this thread, but anyway, here are some of my thoughts on these tracks.
sunite temple background music: this sounds indeed pretty much like 'the lady's house' sliced into separate ensemble chord samples and reassembled into a slightly different melody with some additional harp sequencing, although converted to mono and severely lowpass-filtered, making it sound extremely muddy. this is pretty ugly.
the pc talk song: i don't think there are any significant problems in singing or recording, except some of the fading vocals, that sounded a bit clumsy. the guitar riff is really simple, but it does not bother me much, since the focus is in vocals anyway. it sounds almost like there would be more interesting stuff going on further in the track, but sadly it fades out before that.
the surayah/anomen romance song: pretty nice singing. while i think the guitar track sounds ok, i believe it could have used some reverb or stereo spreading. a pretty irritating thing was the 'binds thee with love' voices in the end of the song, which sound _extremely_ awkward, and kill a big portion of this song for me.
general thoughts on the vocal songs: since these are very vocal-focused tracks, this is not a big problem, but the background guitars in both are really repetitive (just one riff that repeats and repeats), and some variation could have been nice. i do not have any opinions about the lyrics themselves, because i generally do not like music with lyrics, and don't really care about the "messages" of these songs.
finally, it's sad that the full tracks were not available.
