Legally buying music on Android in Ireland

Hi all,

I've recently bought an Android phone. I imagine you can't install iTunes on it? If not, what are the options for buying legal music from your phone in Ireland?

I read about iSyncr. Is it any good?

Ideally, I would be able to buy a song on iTunes (or another site) and have it appear in a music player on my phone without much hassle (without manually dragging and dropping things, etc).
