Dominant online music streaming service Pandora (P) recently announced a new "Pandora Premieres" station, which promises to allow users to listen to new albums before they go on sale. That includes both paying subscribers and ad-supported (free) users.

The move could be a possible defensive play at differentiating Pandora's service, seeing as how Google (GOOGL -1.82%) just launched its own Play Music All Access streaming service. Furthermore, Apple (AAPL -2.19%) is also expected to jump in with some type of "iRadio" service once it gets the licensing deals worked out with record labels.
