iTunes or Spotify
Sometimes, blasting tunes is the only thing that makes slogging through a spreadsheet or a stuffed inbox even remotely tolerable. The exact music client you’ll want will depend on whether you’ve already bought into a service, naturally. For musical neophytes I recommend two programs: iTunes and Spotify.
The iTunes Windows client notoriously sucks, but it gets the job done—and that job includes giving you access to a vast universe of premium music downloads and keeping your iPhone’s music library synced with your PC. Spotify, meanwhile, is an all-you-can-eat streaming service with millions of top-tier tunes available, all for free if you don’t mind listening to a few ads.
