(1) Just Fine by Mary J. Blige
(2) Santeria by Avail
(3) Santeria by Sublime
(4) Race for the Prize by The Flaming Lips

I can explain each of these..
(1) Heard the song in a commercial recently and thought it was a good time. Bought it this morning and it's made me feel so positive about everything, even when things have seemed shitty recently.

(2) I was just telling Kara on Saturday how I've had this love / hate thing with Sublime for a while. I've always had quite a soft spot for this song. Something about the line "Believe me when I say that I got somethin for his punk ass" that's so sweet. Why did I buy the Avail version? They rule and it felt more palatable to buy their version.

(3) See above. The Avail version was awesome but I really wanted the original. I listened to it about 6 times.

(4) So this song... This song has been plaguing me for some time now. I've heard bits and pieces of it on a commercial on Sirius radio but didn't know what it was and I think I may have heard it once in a store at the mall. Anyways, both places that gave me no idea as to who it was. So armed only with my memory of the song I pulled my friend Erik aside and asked him if he knew who it was. Comedically I hummed it and did the drum beat. He left angry and I left still not knowing who it was. Then I get back to my office from lunch today and i heard the snippet on a commercial on Sirius. So I asked my co-worker Sam to go upstairs and grab Erik and have him come down to my car. Sam thought this was strange with no frame of reference as to why. Erik thought it was odd and thought I was going to hurt him. I rewound the Sirius radio (thank you technology) and within 1 second of hearing it he knew exactly what it was. I bought it and listened to it once and now I have that out of my system.
