Me and my elder sister were singing the songs . It 's so nice to hear old school music once in a while and we love Britney 's songs . Then my sister was like , " I have some files on our PC , Britney 's and Nsync 's . Let 's get some more ... " So I went on a download spree ...
According to the above context, answer the following question.
What may be the reason for going on a download spree ?


They did n't have those songs .
