I got a bug in my ear to listen to a song from Glee today. Stay with me; I know you want to click away but I promise this post is about streaming services. I looked up the song – an a cappella version of Katy Perry’s ‘Teenage Dream’ (again, please keep reading) – and was pleasantly surprised to see that MOG had it. I turned it on, turned it up, then realized I should be doing some dishes.

No problem – I’ll fire it up on my phone and run it through a Bluetooth speaker system in the kitchen. There’s just one problem with that – logging into MOG on my phone logged me out on my computer. Come back to the computer later and log back in, go out to get some coffee and log out and in on the phone for the car ride and then back home, log back in, blah blah blah, you get the picture. It’s too much, and it could be so easily solved. Build a feature into both the web app and the iPhone app that allows me to tie my account to my phone so that both can be logged in.

So begins my letter to companies that dream of providing a music streaming service. You absolutely have to make a smooth experience across devices. I’ve been so pleased with MOG that I’ve gone through and deleted a shload of my own digital library, the stuff I just didn’t listen to much or was so ubiquitous I could always get it on MOG (do I really need MP3s of Aerosmith’s Big Ones?). I’m so annoyed with the device situation, though, that I’m ready to jump the MOG ship the moment someone else can do it better.

Another simple thing – make the app more like a music player. I want access to my player all the time from anywhere. I don’t want to have to play a song to see my player, which already has songs queued up by the way. Yes, I could make playlists, but I shouldn’t have to. The whole advantage of the cloud isn’t a cumbersome experience. It’s the opposite. I want your streaming service because I don’t have to keep hundreds of gigs of music around in case my taste changes. I literally dumped 30 gigs of songs last night because the cloud is so convenient. I’d love to dump 30 more.

I constantly struggle to find new music. Yes, there are a million resources out there – blogs, fan sites, news and reviews, venues, torrents, etc. etc. – but there’s so much music in the world that a lot of it ends up sounding the same, and I don’t want something that always sounds the same.

I decided I was going to try a streaming service for the sheer amount of music available. Pandora isn’t on-demand so that was out. I gave Rdio a shot because it was free and had just launched but their selection was woefully slim (they were missing big names like The Arcade Fire among some lesser stuff I was hoping for). From there I turned to MOG and I’ve been fairly impressed. Their selection is good, the iPhone app is passable, as is their web-based player, but I don’t think I’ve discovered all that much.

MOG does have a feature on the web player that allows you to broaden your horizons by including similar artists to the one at the top of your playlist, but it’s just not diverse. It’s the same thing with Pandora. What I want is some sort of discovery mode, where the player throws a wide selection of stuff at you, based not just on the music you’re listening to, but what other people interested in that selection listen to. I would love if it there was even some sort of blacklist feature so that you wouldn’t get the same old mix.

As a for instance, I’m listening to The Hold Steady right now. The similar artist list is about what you’d expect – Modest Mouse, A.C. Newman, Spoon, White Rabbits – all bands that someone listening to The Hold Steady would probably say, “Hey, you’d like these guys, too.” I don’t need that kind of guarantee, though. I want to hear a mix of stuff I might not like and might like and might be surprised I like, and I haven’t found a music service that provides that.

I probably won’t renew my MOG subscription beyond a month because I’m not getting a whole lot more from it than I can get from a Pandora. The on-demand is nice, but the web-player is a little clunky, and I have plenty of music to get through on my own.
