I am only being hard on you guys because I believe in you. A good mixed tape deserves planning. A suggestion would be to tell your friends that you are making a mixed tape. Borrow some of their stuff. This is crucial, especially if you are giving the tape to someone else.
Timing is also an important facet to the planning of a tape.
One wants a good mixed tape to be planned so that the all of the songs planned for the tape can fit and fit in an order that does not compromise the integrity of the theme. One thing that I have found in the art of making a good mixed tape is that many of the songs I have put on the mixed tape are ones that I have played out. Just as the radio and MTV play the same song over and over, you too can be caught in the same trap, we all have been there. My suggestion is to pick a song that is not as familiar to you on the album of an artist you know you want on the tape. Also, when a mixed tape has all of your favorite songs at the beginning, you tend to only listen to the beginning.
