1. Choose a song and get to the countdown.
2. While the countdown is happening, rotate the screen.
3. Observe that the countdown resets but there still seems to be another thread preparing to play the song.

1. Play a full song as normal.
2. When the song is over, press the home button and get out of the app. Do not terminate/unload the app.
3. Load the app again. If it loads in the play screen, press back. If it loads in the home screen then stay. Notice that the Jam button will still say "Jam to: <song from step 1>".
4. Choose a new song from the home screen. I'm not sure if this bug replicates if you choose from the list of recently played songs.
5. Wait it out and see that the song from step 1 plays despite all other UI indicators claim that you should be playing the song chosen from step 4.

Play a song then, before it finishes, choose a new song via the "Choose jam song" button in the player screen. Notice that when the new song is loaded, the countdown display still shows the time left on the previous song.

1. From home screen, choose a song (load the file picker, don't pick from "Recent Jams").
2. With the file picker loaded, switch orientation. Choose a song.
3. Once back to the app home screen, switch orientation again. Notice that the "JAM!" button is grayed out again.

Also happens when:

1. From home screen, choose a song from "Recent Jams".
2. Switch orientations. The "JAM!" button is noticeably grayed out.

1. Load and play song. Let finish.
2. Seek using the seekbar and play.
3. Notice that at this point the time left display (as well as the seekbar position) is inaccurate.

1. Load the app and play a song to completion.
2. Press the Android back button to get back to the home screen. Choose a new song from most recently played list and play.
3. Notice that the seekbar did not reset.

1. Have all four slots of "Recent Jams" filled.
2. Pick any song from "Recent Jams" but the most recent one.
3. Notice that the queue positions remain the same. Expected behavior is for the song chosen in step 2 to become the new most recent song.

There should be one and only one song playing at any given time.

Consider this:

1. Load a song to play.
2. While the current song is playing, press back. You should be in the home screen with the "Jam to: ..." button loaded with the name of the song currently playing.
3. Press "Jam to: ...". Notice that the countdown will play along the current song and then the song will repeat.

Also,

1. Load a song to play.
2. While the current song is playing, press back. From the home screen choose a new song to play and play it.
3. Weird stuff happens, ultimately leading to both songs playing side-by-side.

For this part, the behavior should be as if user tapped "Choose jam song" while in the player view.

Couple of observations:

1. Some songs don't eat up the complete seekbar.
2. Some songs still don't end in "00:00". Check if loading new songs while in play screen has any bearing on this.

Screenshot exhibiting both observations (note that the song displayed is over):

1. Have a fresh install of the app.
2. Play a song.
3. After the song has played, press back.
4. Notice that the home screen still does not list any recent file.
5. To get it to list a recent file, tilting the phone (so it changed orientation) and going back to original orientation works.
