These pieces are not actually 'unreleased'. They were done by Yanni for the exclusive use of different networks for sports events. For that reason, Yanni is not able to release them on CD and the broadcasting companies that own them have never released them.
Many of Yanni's older pieces are available for purchase on sites like iTunes, Napster, Rhapsody, etc. But, be wary, I noticed several pieces on Rhapsody attributed to Yanni that aren't his. If it doesn't appear on one of his original albums, it's probably not by Yanni with the exception of Mother Night.
What About some of yanni's older songs that fade out? Is that the whole entire song once it reaches silence, or is there more recording after that?
I'm looking for the orignal unedited recordings of songs such as street level, paths on water, days of summer, looking glass, strings, turn of the tide, walkabout, nightbird, dance with a stranger, etc.
Is there any websites that give song parts that are unreleased(eg. after a song fades out)?

I've never heard of one and they would have to have access to the original master recordings which no recording company in their right mind would ever allow out.
The pieces you are referring to might or might not fade out, would depend on how they were recorded. I suggest, to know what pieces were like when Yanni released them you should get the original recordings. The oldest five albums are out of print but you can often find them and all of the original albums on EBay.
