I have the same problem, but the log is different :
01/14 14:24:53 Trace: [Broker:Media] [music/query] query returned 31 Sooloos.Broker.Api.Tag(s)
01/14 14:24:53 Trace: [Broker:Media] [music/query] performing tag query
01/14 14:24:53 Trace: [Broker:Media] [music/query] query returned 31 Sooloos.Broker.Api.Tag(s)

01/14 14:24:53 Trace: [Broker:Media] [music/query] query returned 31 Sooloos.Broker.Api.Tag(s)
the loop is in the tag query.
the tags are underneath Live Radio, how bizar.
So tomorrow History will cause a loop, I presume.
I uploaded some logs from yesterday with the radio loop.
