3rd gen albums come in CD, download, and streamed format?

Physical is the physical album. Download is the digital album. Both count as sales, streaming doesn't, unless you're talking about album-equivalent units. But the numbers people use are usually only for physicals.

It's like buying a game, digital or physical, both are sales. Or buying a movie, digital or physical, both are sales. Or buying a book, digital or physical, both are sales.

Downloads and streaming are counted differently though.

I believe for Billboard for instance it takes 10 downloaded songs to count as one album sale and I believe it takes 1000 song streams to count as one album sale.

what, that is very interesting
