Ray's Records: Artists Beginning With N

I own a silly amount of LPs, CDs, DVDs etc, so thought it a good idea to catalogue the recording artists in my collection.
Some real oddballs in here that don't really fit with my musical tastes, mostly obtained when purchasing job lots of LPs from people, who, for varying reasons, wanted rid of them.
Also, some artists/acts are conspicuous by their absence, these anomalies will be corrected by getting more records!
