First of all, you should put the band name first, then a hyphen, then the song title. Like this:
The Descending Testicles - Jerk Off on the Flag
Second of all, what you put together wasn't a mixtape. It was a poorly hashed-together amalgam of songs you like. These things are not the same. I mean, shit, I could put together one of those in a couple minutes. In fact, I will.

There.
I made a mix. Hot damn, that's awesome.
Or.....not.
A mix takes a lot more than just throwing a bunch of songs together. You should go into the mix with a theme that all songs should adhere to. You could make a summertime mix and have lots of summery songs (The Breeders - "Cannonball" for example). You could make a dreaming mix and have lots of songs about dreams or sleep (The Weakerthans - "Prescience of Dawn" and The Arcade Fire - "Rebellion (Lies)" for example). You could make a "fuck dirty hippies" mix and include songs like California Uber Alles by the Dead Kennedys. I mean, really, the possibilities are endless.
Not only that, but you should try to keep the tracklist assembled in such a way that it feels like one coherent body of work, the mixtape, rather than a bunch of singles randomly thrown together. You shouldn't follow up Sigur Ros with The Epoxies. It just doesn't work. You can have both on the same mix, but you should space them apart, and have some songs that transition between the two, so it's not a sudden shock when you go from something slow and atmospheric to fast poppy synthpunk.
Also, one song per artist per mix. I don't care if you love the shit out of Cake, throwing two Cake songs on a mix is a no-no.
Also, if there's a song that you damned well MUST HAVE, then use that to determine the theme for the mix. Don't just toss it in haphazardly and say "well, it makes me happy." That's just lazy.
Now that I have officially ruined this thread, does someone want to go get me a sandwich?
