I seem to have maxed out the number of songs you can keep track of in one URL. See: http://bit.ly/10kZyKg which loads 130 songs, but my playlist is 156 songs long (until I close the tab I presume).

I'd love to see:

1. Way to save a playlist as a shortened URL for sharing purposes.

2. Previous/Next buttons

3. Max-width for the playlist that keeps each song on one line

4. A means to save several playlists in one place

5. More obvious shuffle/repeat buttons

Overall, I really like the simplicity of the interface. I hardly comment on HN these days, but I wanted to provide some constructive feedback for you.

Best,
