I already have a laptop with enough memory and I hope for your program. I have over 3000 records but use only about 400 when I travel.
The program is primarily geared towards callers, and the music portion of the program is just one part of the program.
As a round dance cuer, you probably don't really need my program. Callers, on the other hand, appreciate the music portion of the program because it can do automatic looping for patter records.

The CSDS program, on the other hand, has a few features that you may find useful:
You don't need to worry about how much memory your laptop has, but you do need to worry about hard disk space. Although MP3 files are much smaller than WAV files, they still do take up space. One gigabyte of space can hold about 600 45-rpm records.
If you're still interested in CSDS, I could make a version of the program that only included the music section for a reduced price (perhaps US$100 or so).
