If you missed some of the big headlines, don’t fret. Here’s a roundup of what dominated Re/code this past week:

3. Apple bought the radio app Swell for $30 million in an effort to beef up its much-maligned podcast app. Apple also purchased the book recommendation service BookLamp for an undisclosed sum, and finalized its $3 billion purchase of Beats, which will eventually leave 200 Beats workers without jobs.
4. In the category of non-Apple M&A this week, Nordstrom shelled out $350 million for the online men’s fashion company Trunk Club, and Alibaba invested $120 million in the free-to-play gaming company Kabam.
