I have the same problem...so I'm going to horn in on this thread and ask for the same!!! HAHAHAHAHAHA!!!!!
Which means, Ryan, you have to give ME suggestions. And here are mine for you.
my first would be Metric but you already have that....you better have all of Emily Haines' solo album stuff too!!!!! If not...get that. I think we have similar tastes, at least from some of the things you post, so, you might not get a lot of use out of my list because you have a lot of it, but I'm going to try. I put my number 1 favorite song by the artist next to them, as like a starting point. ... Also I bolded the ones I think are most important.
