Just rip your albums to a single FLAC file with an embedded cue sheet.
Listening to them in 7zip will cause more strain on your CPU and I assume you're using a pentium II so you definitely can't handle that.

Anyways software is for lamers, just use cds and vinyl records.
If you absolutely have to have digital then use an iPod classic.
