TIP: If we haven't answered your question yet, and it's about a certain artist,

type into the URL bar "mediaexposed.tumblr.com/tagged/the+artist"

and if that doesn't work type

"mediaexposed.tumblr.com/tagged/the_artist"

[adding a + or _ where there's a space in the name.]

For example:

"mediaexposed.tumblr.com/tagged/lady+gaga"
