Mix tape songs needed?

I'm in the process of making a mix tape and as the title implies I'm having trouble finding songs to fill out the rest of the CD. That seems simple enough but I'm trying to have all the same type/genre of music throughout the CD. Bands that I'm planning on using include Ronnie Day, Dashboard Confessional, Secondhand Serenade, Time and Distance, and Jack's Mannequin. Any similar artists would be very much appreciated.
