If you have installed Picard in Arch Linux, and you try to explore the CD "CD Lookup", you may get an error like this:

Error While reading CD

Error opening library: libdiscid.so.0 cannot open shared object file: No such file or directory

That is because, you may have not installed libdiscid.so.O, so go ahead and install it from yaour.

yaourt libdisc

I do not have a very big mp3 music files collection, just 2 to 3 gigs of them, but I have made it over the years, and some of the original CDs are missed, so I can not import them again.
