I would also like to request support to read from ZIP files, only reading no writing so the files don't change.
This way I can organize my files better and put one album into a single zip file.
I only need zip file support, rar/7z especially with solid option wouldn't be any good for this.
Memory usage is not a concern even with flac files, extracting a full track or even the full album to memory should not be an issue with the amount of memory PCs have nowadays.
