Similarily, Belle and Sebastian pretty much define twee (or, sub) pop. Hell, Shin’s label even has “pop” in its name.
Now, before suggestions, check out the following sites. Downloads, places to listen, etc - by far my favorite way to get into new music. They are in decreasing order of versatility, as I see fit.
www.pandora.com - Probably have seen this by now, go now if you haven’t
www.3hive.com - Collects the MP3s from bandsites the internet over
www.epitonic.com - MP3s, but hard to navigate and not really updated anymore
www.subpop.com - The major label if there ever was an indie equivalent (Shins and a thousand other awesome bands are on it)
www.jr.com - For listening to quick samples; works good for me, although YMMV
www.pitchforkmedia.com - The pretenious, hipster wankers who every pretenious, hipster indie kid pretends to hate, they are good for learning a little about the bands
With that out of the way, let’s do some suggestions, shall we? I’ll attempt, best as possible, to get links to (free, legal) mp3s with every one.
First, you seem to really enjoy twee pop. The Shins sound completely different than any other band you care to mention, but there are several other distinctive bands that have the same mellow, poppy sound you are looking for.
I’d say first, you should check out some singer-song writers that everyone seems to love. Elliot Smith (look at 3hive above for MP3s) is a classic mention, but he is far more darker, far more mellow at times than the Shins. Still, worth a mention.
If you just want fun, poppy, amazing stuff, look no further than Tilly and the Wall. Mellow, upbeat, fun - their precussion is a tap dancer, for instance. Try “Let it Rain” and “Bessa”, I’d say.
I suppose I should by now mention Belle and Sebastion, which from little I’ve heard is some what similar, but I am not as familar with them as with others.
The Robot Ate Me might do wonders for ya’, or you just might hate it. Think the Shins, only slightly slower, sometimes more complex. “On Vacation” is probably your best bet out of those listed.
Finally, there are many bands which I can guess you’d like based on everyone else’s preferences who also happen to like the Shins, but they share nothing in common with them. Continue with an open mind…
Beat Happening - Cute simple love songs, although none on that page I can recommend above others they have done
Bright Eyes - Sometimes pretenious, sometimes entirely unlistenable, but also at times fairly good. Try to listen to “Waste of Paint” or “Bowl of Oranges” sometime (see the “JR” website above)
Neutral Milk Hotel - No MP3s online that I’m aware of (try Pandora), but they are an Indie staple. Most people love them, but there are a few who hate them entirely.
Devendra Banhart - Really, really folk. Mostly laid back and mellow, he can find build a tune out of anything.
Postal Service - Another indie staple. Off the label as the Shins, their one little record has a cult following rival only to Neutral Milk Hotel.
Iron and Wine - They covered Postal Service’s “Such Great Heights” for Garden State. He is superb mellowness.
Then, here are some random names I don’t feel like getting links for now, so I suppose type them into Pandora: Arcade Fire, Wolf Parade, Architecture in Helsinki, Clap Your Hands Say Yeah, Mountain Goats, the Unicorns, and the Winks.
That should get you started. I’ll expand on anything you need, provide histories if you want them, or will give more recommendations on request. I’m a huge, huge fan of indie music, and the Shins are just another one of my favorite bands.
I’ll also suggest to really stick with something you may think you will like, because probably 60% of the music I love the most I didn’t like on the first couple of listens. Paradoxial, I know, but the truth.
