Voting Question: Music player with Zune & ipod?

Hello, I have a 1gb ipod shuffle I got a few years ago and an 8gb Zune, however the appropriate music players for these two separate mp3 players takes quite the toll on my computer, as does having to input my music into two different players.

So my question is this, though I'm not really expecting a fruitful search to be honest since I've been looking for a few days now, is there a music player out there tht will let me input songs onto both my Zune and my ipod shuffle?

Thanks for any help :D
