Well that now makes the second Twitter product without an Android launch strategy. The first, Vine, looks like it'll flame out by the time they ever toss a half broken app across the corporate firewall. Are they running out of cash or something? Their competition doesn't seem to be having a problem with supporting more than one platform.
Edit: I'd also like the point out the irony of hitting "Play Full Tracks", picking Rdio, then immediately being presented with a Facebook logo and login option but no Twitter SSO. /facepalm
