Upon further review, what happened to our listings was too much success. We were #1 and #2 under 5 top music searches. Both those positions fell. Alta has been doing this alot with #1 and #2 listings. I think they have a tracker on the number of searches a page comes up under and then nuke the listing when it gets to a certain point. I've seen #1 and #2 drop out of sight many times in the last few months while the rest of the listings remain ok (under all bigger searches).
