"If you put all the songs together that I've written on band records, and put it up next to my solo record, there's definitely a different kind of feel than Billy's songs"

James Iha is describing the distinction between his solo work and the tunes he composed for the band he was in, probably the Smashing Pumpkins. He is suggesting that his solo work has a different feel than the tunes he composed for the band. This might be because his solo work is more personal and reflective of his own individual design, whereas the tunes he composed for the band were more collective and needed to fit within the band's overall sound. It could likewise be because his solo work is more experimental and has a wider variety of influences than the tunes he wrote for the band. Whatever the reason, it is clear that James Iha believes his solo work has a various feel than the tunes he composed for the band.
