I got an invite to Rdio.
First impressions after playing with it for 20 minutes:
Ooh, it’ll actually try to stay in sync with my iTunes library. Doesn’t upload anything, just scans iTunes to match things up. That’s nice.
AHH ADOBE AIR! GET IT AWAY GET IT AWAY!
After syncing it found about 7500 songs, which is ok for an early service, but isn’t quite the >30k in my collection.
The Adobe air player is alright, but will drive you crazy if you’re used to keyboard shortcuts from Bowtie or Coversutra.
It fails the Pink Floyd test.
You can share music on social networks, although really it’s just a link back to the Rdio page. Spotify seems to be the only company that gets this right. Sharing on other services feels more about marketing the service than sharing music with a friend.
Right now it feels more like a Lala replacement than an iTunes replacement. You can listen to as much music as you want through their website for $4.99 a month. But if you want access from your cell phone (including through Wifi, I assume) then the plan is $9.99 a month. The problem with these streaming services is that your collection is limited to what the service actually has a license for. They may not have your favorite indie band or that singer you found on Bandcamp.
But if you don’t care about stuff like that then maybe Rdio is up your alley.
