Point out to me how purchasing music is free.
Android has about 4 equivalents (because Android is, if nothing else, full of options).
A. Spotify, which is an unlimited music subscription system, allows you to play whatever music they have on their network, in addition to syncing over wifi any songs from your PC that may not be on their network. It's actually easier to use than iTunes. Bonus points: you're not limited to Android, you can use Spotify in a LOT of places (PC, Mac, iOS, Android, Blackberry, and even Roku boxes).
B. Google Music will sync your music to the cloud (one click, literally). From there, the Google Music app on your phone will let you do literally anything iTunes did, and easier.
C. Many apps can treat Android phones as traditional MP3 players, letting you sync them using their own software (example: Winamp).
D. If you absolutely, positively had to, you could still use iTunes to sync to Android, using one of a handful of different Android apps to pull it off.
The first option is my preferred option because there's literally no easier way to sync than something that syncs automatically, in the background, using music you didn't even purchase (just $10/m instead of $1000/year it'd take to buy the music I listen to).
iTunes Match isn't, genius. You know, that magical cloud **** that isn't really all that magical? (Because it fails half the time and can't stream worth **** on cellular connections)
