No cause for concern here. foo_shn is the SHN decoder plugin for foobar2000. This is jsut giving you a little feedback about the SHN file:

INFO (foo_shn) : cannot find / read external metadata tag file

This means that there is no .tag file associated with the SHN file. Since SHN does not have any inherant support for tagging, foo_shn can write metadeta to a .tag file. This obviously doesn't have one, but that's fine.

INFO (foo_shn) : cannot find / load external seektable file.

Again, foo_shn is looking for either appended to external seektables. It didn't find any, which means that the SHNs are not seekable (in most other players). The line below that, however, shows just one reason why foobar is the best player out there: it is making up for the lack of a seektable by generating one on the fly so that the end user will never have to worry if the original files were seekable or not.

The foo_bitcompare plugin is just telling you which files it is comparing, and then returns the result that no differences were found. You've successfully completed an SHN > FLAC conversion!
