Five Records:

5pb. Records:

Following a bit of parent company restructuring, Five Records became 5pb. Records on December 2007. Therefore any albums released after that date (except for one enclosure) should be linked to 5pb. and
not Five Records.
The confusion between the two is possibly due to the fact that Five Records was usually listed as "Five Records / 5pb.", with 5pb. being the parent company.
In any case, since label discographies are listed by release date, a glance at Five Records' page should quickly tell you whether there's any mislinked albums. As of now all the links should be correct.
