It's the little Pandora app that makes a very big difference in how you use the music streaming service.
I've been a big Pandora fan for about a year now. Lately, my love has been getting steamrolled by various Spotify evangelists, but for me, I don't feel like I've really gotten everything I can out of the Pandora experience. As you probably know, Pandora is internet "radio" — its killer technology is a predictive algorithm that can take a song, artist, even an album title and turn it into a stream of music, by using the song's DNA. This is the "Music Genone Project"). You provide an input based on what you like — say, Ozzy Osbourne or Gustav Mahler — and...Pandora's box of music is opened!
Pandora has effectively replaced iTunes as my go-to music resource. iTunes is fine, but I've always liked radio better than the self-programming that more self-contained music formats entail — everything from mix-tapes in the 1980s and '90s to iTunes playlists now. Like the radio, Pandora does the work for me. (See, this is how I wound up working at a radio station!)
