Music Library

Overview

At app launch, the user is presented with a library. The library should include the following options:

• Playlists
• Podcasts
• Audiobooks

Only applies to music files (not the above), filters your music based on metadata (ID3):

• Artist
• Song
• Album
• Genre

Layout

The library lists should be visual and typographic.
In portrait orientation when the user clicks on any category they should see a list formatted in this manner:
[album art] text based on filter type

In landscape orientation, the view should be more visual, more focused on album art. When the user clicks on any category they should see:
[large album art]
small text based on filter type

Quick Browsing

Each browsing list should contain:

• Search input field, to search the entire music library
• Quick index browsing: A-Z column, when the user touchs a letter the list quickly scrolls to that letter in the list
• Inertial scrolling, the fast the user touch scrolls down the page, the quicker the scrolling becomes.
• Back Button: back 1 level

Sync

Playlist Support

User can (manually) import (copy) a playlist from popular desktop apps such as iTunes or Windows Media Player.

Management within the device.

The user can:

• 1. create a new playlist, place tracks within this playlist
• 2. organize the tracks in existing playlists
• 3. rate music

Would be nice to have...

• 4. edit the metadata
• 5. the system tracks the quantity of playbacks for each track
