A few years back I was listening to pandora and thinking it was the best poo since napster. It didn't take up space on my hard drive, and it was tunes for the background while I was shooting people in video games.
So I made an account, and like most accounts the first 30 days were magical. Everything worked great, nothing went wrong, I could skip songs that sucked or downvote them to oblivion.
About two months in, I hit their "free listen limit" which I believe was 20 hours total in a month.
I game pretty compulsively, so I hit that limit fairly early in the month. I didn't like this, so I contacted their support department to cancel my account. At first they tried to retain the account and tell me to just not use it, but I didn't want to be counted as part of their user base.
Their support department was surprisingly understanding, and closed my account as requested.
Since then, they have removed the limit. I signed back up, and am very happy with the current performance. I'll post back in this thread in march if things go shitsville.
I've yet to hear an ad, and the only limitation I've ran into is that they stop the music every once in a while to check if a human is actually listening. This is easy enough to fix between respawns, so it's a good choice for the gamer.
Plus, you decide the content unlike slacker. On slacker you're using a predefined set list made by a DJ. That's fine if you get a good DJ, but their dubstep DJ, "Party Ben" doesn't really seem to understand what he's doing.
