Add UI for selecting and displaying audio files with metadata

Add a user interface to select a folder containing audio files and display these files in a table.

The table should show tag info including track title, artist(s), album, track number, and release year.

An additional panel should display the remaining info for a selected item, including artwork, audio file header info, file path/URL, and channels.

Display of audio header info e.g. encoding type, channels, sample rate, and bit rate not essential. Since the main aim of the application is to search for metadata online.
