I believe it depends where you are. For example there's never any streams on LiveATC from the UK, when I googled it, it seems it's illegal to listen in to ATC there. By contrast here in Victoria (in Aus, states set their own laws re radio, and never looked into other states) tower frequencies seem to be freely available.
But yeah, unless you want to camp out, you'll likely be getting what's on liveATC anyway lol. Like I say - I recommend VATSim or IVAO for learning and practicing, it really helps understanding liveATC feeds. A trial of pilot edge might be worth it, but I personally didn't think it was worth $20-35 a month - isn't the point of this really not to waste money learning coms whilst you're in the cockpit? ( and actually controllers on vatsim are more forgiving of noobs lol) Make your mistakes with a sim, have the skills for RL
