any harvey danger and soul coughing - circles, but you're off to a great start.

and counting crows

I don't know if people have forgotten them. I guess it depends what radio stations you listen to. Still, I can provide a few suggestions to increase your alternative base:
Bush- "Greedy Fly" or "Swallowed"
Sebadoh- "Flame"
Feeder- "Insomnia"
And don't forget Collective Soul and Dishwalla.

by asking for feedback, you kind of missing the point of "jams everyone else forget about but me", but that's forgiveable. big fan of the picks from pavement, the breeders and better than ezra. the trews is from the 00's for sure.

additional suggestions: gin blossoms "hey jealousy" (if i could only pick 1, this would be it), goo goo dolls "name" or "naked", screaming trees "nearly lost you", blink-182 "dammit", filter "take a picture", the offspring "self-esteem", hole "doll parts". then there's the holy trinity of nirvana, pearl jam, and the smashing pumpkins ...

There will always be a room in my heart for Cannonball and Cut Your Hair. A dirty little room with overflowing ashtrays and empty bottles of Mount Gay Rum.

How about:
"Divine Thing" - Soup Dragons

"Stay" - Lisa Loeb

i made a 90's alt.rock mix not too long ago! you can check that out for suggestions, if you'd like!

a good mix, except the trews song came out last year

I love these tracks too! Keep rockin to the 90s alt.

These are songs people have forgotten?

I don't know about that.
Seems more like songs everyone knows all the words to and talks about to make themselves look cool in front of their friends.

Good mix...don't change the songs. Maybe change the title.
