name of the song

what is the name of the song that played around 9 20 pm in eastern time it sounds like mexican music sort of , kinda like harmonicas

if my time zone conversions were right, 9:20 pm in your time must have been right at the start of Trance Mix Mission 128 with Macarius (15-10-2007) [REPLAY] (started at 9:18 pm). digging out the thread and reading the first comments (http://forum.afterhours.fm/showthread.php?t=7974) it appears to be right, and from the tracklist (from http://torrents.ah.fm/details.php?id=1180), this should be:
01 Samim - Heater (Claude Vonstroke Mix)
which is also what i've immediately thought of when i read the word "harminca"
