A very good feature that is missing on all mp3 players is what i'll call the "cross navigation" :
When listening to a title, having the ability to select:
- Stay on this style
- Stay on this album
- Stay on ths artist
...
That way, you can listen to titles (in random mode for instance), and when you like or remember a good artist, clicking on "stay on this artist" will then only select titles from him...
Later, selecting "stay on this style" will allow to select all songs in the current style.
example:
I listen to titles in random mode
I hear a song of a Jamiroquai CD that I like very much and i want then to listen to this album: I choose "stay on this album"
few songs later, there is a song of this album that is tagged as "reggae" and it makes me want to ear reggae music. I select "stay on this style" and it moves me to all reggae musics, and so on
What do you thing about this ?
