Music channels

After a recent "upgrade" on the music channels, they're awful. When switching to a channel it takes a full 20-30 seconds to load, and the quality has been terrible, music will play for a bit, then the sound cuts out then sound again for a few seconds then dead silence again. It's really awful. Also, if I'm on a music channel and I hit the DVR or Favorites button it automatically switches channels, usually to the last one I was watching, which is just stupid. Thanks for screwing up a nice feature.
