Music Director #1 | - User found the drag and drop interface to be intuitive and easily learnable, but isn't familiar with the fact that file start importing as soon as the mouse button is released. Instead, user searched for an "OK" button to start importing officially. This is a tradeoff we made to achieve more efficiency, but sacrifices some safety because the user may inadvertently drop the wrong file on the interface.
| - User recognized the play button beside the track right away (learnability)
- User's single click on the play button starts playing the track right away (efficiency)
- If user clicked on play accidentally, a pause button appears in place of the play button to stop track (safety)
| - (U) had some trouble locating the trash can because it was placed far away from the user's line of vision (learnability)
- (E) quickly found the "X" delete button beside the uploading album (safety)
| - Both interfaces lack affordances in terms of what is editable and what isn't, user had to experiment by single clicking on the fields (learnability)
- User noted the directly editable fields are very convenient (efficiency)
- User noted a mistake in adding the genre can be easily fixed by clicking the "x" beside the genre tag (safety)
| - User was confused about how to "approve" the album on both interfaces because he did not associate approval with the "checkmark" button (learnability)
- Again, a tradeoff was made between efficiency and safety: single click on the "checkmark" button will approve the album immediately (efficiency)
- User prefers a confirmation message (safety)

Music Director #2 | - User really likes being able to type in the URL instead of downloading then dropping the file (efficiency)
| - (U) Had a hard time finding how to open the album information, tried to click on "Recently Uploaded" tab (learnability)
| - For a long time, user had trouble finding the trash can (learnability)
- Tried clicking on the trash can but surprised to find it deletes without asking her to confirm (safety)
| - User figured out how to edit fields rather fast, but not sure how to "save" the entry (tried clicking inside the textbox when she really just wanted to exit the textbox (safety)
- Tried clicking on "checkmark" icon, which could cause further problems as that will approve the entire album and make the edit screen disappear altogether (safety)
| - User used the comments section before approving, found it to be a really good idea

Music Director #3 | - Did not understand the "drag and drop" instructions (learnability)
- User had trouble uploading the files due to lack of clarity in instructions and also did not understand the “Today’s Upload” tab, tried clicking on other tabs (learnability)
- User struggled with learnability insomuch that efficiency and safety were not concerns
| - User found the play button very quickly and had no other issues (learnability)
- (E) User liked having all the information in one place (play button, album information etc.) for all albums
| - (U) User saw the trashcan and assumed that it works the same way as the Windows Recycle Bin (learnability)
- User can drop multiple files into a trash can, is there a way to quickly delete multiple albums? (efficiency)
- User likes a place where you can open the trash can to look at deleted albums (safety)
| - User looked for a save button to confirm edits to the field (safety)
- User likes the add genre feature to allow for sub-genres and easy deletion of wrongly labeled genres (safety)

"Elf" | - Our interface did not make it explicit that users are to drop zip files directly (learnability)
- User noted that he will want to drop multiple files at a time (efficiency)
- User tried to unzip all files first then drag and drop the content directly onto the KaJaM interface (efficiency)
- User also noted that there doesn't seem to be a way to cancel a file dropped accidentally (safety)
| - User was confused that the right side of the screen was completely blank, and instead clicked on "recently uploaded" tab to look for the tracks within currently uploading album (learnability)
- Quickly found the play button to preview each track User tried to unzip all files first then drag and drop the content directly onto the KaJaM interface (efficiency)
| - User wants a feature that allows for stopping the import but not delete it
- Had trouble deleting all 3 separate tracks quickly, just deleting one at a time (efficiency)
- Don't need confirmation message, especially if it acts like a recycle bin like on Windows (safety)
| - User suggested offering more affordances for single click because he is a "double-click" guy (learnability and efficiency)
- What if there are different artists in each album (compilations are very frequent), want the ability to change the artist name for each track versus for the album (efficiency versus customizability)
- Various artists for the entire album, but separate artist name for each song
| - No issues with learnability, efficiency or safety but want to see what he has approved during the current session (want to see what other people have uploaded recently)
