Rhythmbox is the default music player on Ubuntu. I've heard wonderful things about Amarok, however I still have yet to try it out. Rhythmbox is great, even makes me not miss Winamp so much anymore. It does all the normal stuff, like play my music, let me search through the library, sort by various things like artist, album, etc. It even keeps track of how many times I play a particular song. Shows which music on my list I actually listen to.
So I finally caved and bought an iPod not too long ago. I dislike Apple nearly as much as Microsoft, but I figured I'd give it a shot. I plug in the iPod and...nothing happens. Doesn't detect it or anything. So I do a quick Google search for "ubuntu ipod" which brings me to a page that says the iPod must first be formatted before I use it. Ok then, I reboot into Windows, download iTunes, and format the thing. Cool, so Windows now sees it. I reboot into Ubuntu, and what happens? Something! Rhythmbox detects it and pops it up on the side with all the playlists and what-not that I can dump stuff into. So I can drag and drop music onto my iPod now.
So hooray, I can mindlessly stare out the window with white earbuds in my ears. Speaking of which, I wonder if my huge headphones will work with the iPod, I like those better.
