Bill,

I agree. I have judged about 1800 pairs of songs. Unless it is really bad, I always listen to at least 30 seconds; often skipping ahead, afterwards, to the 2:00 and 2:30 spots, approximately. Sometimes a chorus or bridge can really add something to an otherwise decent but not special song. And, as has been poiinted out, most intros are close to 15 seconds...many much longer.

But, if the song gives me absolutely nothing but intro, or even less, for more than 30 seconds, I am done with it. Just my take.
