It's very confusing when you click "Show All" on Albums and you a get clutter of singles and Albums especially when you click on "Show All" from Songs and you only see songs. I get that singles are a type of release but my brain is setup to expect Albums when I click "Show All" that's on the Albums row. I think the are 2 possibly better options:
1) Have the drop down pre-selected to Albums and I can change it to All or Singles
2) Change the drop down to a link that says "Go to Singles" and separate Albums and Singles into two sections with Albums on top
