Seamless lets you transition from playing music on your Mac to playing music on your iPhone or iPod touch -- or vice versa -- in a single tap.
It's 9AM, and you're at home getting dressed to go to work.
We've all been there, so you know why this sucks: you've interrupted the song! The groove! The beat! You just killed it.
Meet Seamless. When you're ready to transition music from iTunes to iPod, tap Seamless on your phone, and boom. The music fades out on the Mac, and fades in on the phone.
Groove: preserved.
Beat: better than ever.
Rock on.
