Dynamic Playlist

Hi,

We've a scenario, where we want to build playlist at run-time. The website will load the categories and category songs. When the use clicks on specific category, the website will display the songs list within the categories.

For each song there will be an option "+ (Add to Playlist)", this action should pick-up the song detail and add to the playlist. The use can select as many songs they want to add in the playlist.What is the best design for the playlist scenario?

Please advise.
