@jefftheworld: We haven't considered such a download of single files as the main purpose of this is to act as curated "mixtape". Single MP3 files can be easily obtained via the mighty "Stone Oakvalley's Authentic SID Collection (SOASC=)" @ www.6581-8580.com. SID files are available on the HVSC @ www.hvsc.c64.org as you know for sure.
