[Bug] If you accidentally click multiple playlists, it is possible to open multiple of them

[LuisACorreaCSUMB]

This can make it hard to get back to the main menu as you will have to back out of every opened one

Repro Steps:

1. Tap a playlist that has a larger amount of songs
2. The app will probably hang at that moment
3. While it hangs tap another playlist

Expected Results

The first playlist should only be loaded in

Actual Results

All playlists tapped are loaded in

Potential Solution

Change up the ordering of how we load in new data for each playlist. More so, navigate immediately to our playlist and throw some loading indicator on the songs list while they come in. Also, when a playlist is tapped, potentially set a flag that blocks all other playlists from being tapped.
