Personally, I've been loving Beats1. I didn't think I would, because I was assuming it would be 100% pop music ... although I do like Ke$ha.
Turns out, I've not heard a single time that Taylor Swift, Selena Gomez, Justin Beiber or Miley Cyrus played on B1. Yes, they do play lots of Rap/Hip-Hop and R&B. If you don't like those genres, then Ebro's show is probably not for you. Julie Adenuga (sp?) plays a nice mix of R&B and other stuff. I've discovered a few new songs through Julie and Ebro's shows. iTunes will get a few dollars from me the next time I buy a couple of songs.
To me, the best thing about Beats1 is that it's "human". I stopped listening to music on the radio because it was becoming a pop-fest with annoying DJs and overly-autotuned vocals. But just listening to playlists is very lonely and sterile. Beats1 has brought back a personal touch. Yeah, the DJs can be annoying when they talk over the music, but many times, they inject humor and conversation into the listening experience.
The other day, they had a show which played an entire live album of Bill Withers. I had never heard of this guy, but the album was very entertaining. And the DJ only spoke in between the track to intro the next song or add some interesting tidbit of information. I don't think I would have gotten that type of entertainment from any other source.
I think this replay feature is going to be pretty cool for me. I'll be able to listen to the shows that I miss because I'm asleep or at work or whatever.
Can't wait for Beats to expand their number of radio stations.
