Thanks for explaining all that. I HATED the new Billboard look on first sight, and couldn't (and can't) understand why when you click on "charts" they don't just list all their charts and let you, you know, go to the one you want. As it is, they'll give you a few of the main ones, and to find your way to, say, the adult contemporary chart you first have to go to one of the charts they do give you, click on it, find a song that may also have charted adult contemporary, look at where it says "also charted on," and hope that adult contemporary is one of the top five charts the Billboard decides to list for the song.* Maybe there's an easier way, but if so, it would help if they'd tell us.

But I did also discover that Billboard now lists all the songs on the Hot 100 rather than the Top 50. So that's a plus, and with the gizmos you point out apparently a lot of other info is available that formerly wasn't, or was formerly available only when piggybacked on data from Allmusic. I guess I'll go play there to see what I can see. I mean, it used to be a bitch trying to find when a current song first entered the charts. You'd have to hit search, hit the charts option, then basically guess how many pages you'd have to go to find the week the song first entered, would take many minutes.

*And then they only give you the top 15, reserving the rest for the paying customers.
