Scottish rocker KT Tunstall longs for a split with her boyfriend - because it will give her inspiration for songs. The singer briefly split with long-term boyfriend Luke Bullen - and it inspired her to write song Someday Soon which features on new album Drastic Fantastic. And she now plans to have more arguments in a bid for musical success. She says, "Luke and I split up for a day and that's when I wrote the song. In fact, we're been trying to think up other reasons to have another big argument so I can get some songs out of it."
