I know Slacker is bloatware of sorts since it comes on the Bionic, but I've listened to it since my D1 days and love it. I updated it on the Market (it doesn't show up in your apps to update, you have to search for it, then click update) and it is very much improved. The newest feature is that it will preload the next few tracks so that if a song ends or you skip the current song, it will go right into the next song with no pauses. This feature can be enabled or disabled in Settings within Slacker. Enjoy!
