Using services like allofmp3.com in Switzerland was and is perfectly legal (if you can find a way to pay for it).
There's a reason for that: Swiss legislators believe that it can not be up to the user of a download site to judge if this site is legit and is licensed to sell downloads to Swiss customers.
This doesn't mean that uploading is allowed. As soon you upload files or even fragments of files you crossed the line into illegality.
The whole "It is very terribly illegal what you're doing here, downloader!" hokum was basically pushed by IFPI and the content industry.
It's a lie (at least in Switzerland).
