Indeed, Frank - good comparison. Stephen Potter advised in 'Lifemanship' [I think it was] that if you are ever fortunate enough to meet anyone who actually sez "I don't know anything about Art but I know what I like", you should reply in a plonking tone "If you don't know anything about Art, you DON"T know what you like". Mutatis-mutandis, a similar response might be made to the "If I sing it it's folk" claim.
