I like all kinds of music from traditional folk, singer/songwriter through to pop, classical and jazz(some). Some I play better than others, some I shouldn't play at all, but it really depends on what mood I'm in. Although I do keep looking, I'm finding less to interest me from the "new" side and often prefer to trawl the "old" for songs that are "new" to me. If I was forced to pick between blues and folk my first instinct would be to pick blues but, having played in a (purely)blues band, I think I might find it a little limiting and would probably opt for the folk as that covers such a broad range of styles.
