They probably replaced all the good songs in the second half with all these fillers, so they can put them on the re-release after they run out of single-worthy songs.
Just because all songs are not single-worthy in the album, it doesnt mean they are fillers nor they are bad. Every song in Prism has its place there.
I'm here for at LEAST 6 singles from 'PRISM', and another 2 from a possible re-release, if they go ahead with one (just like 'Teenage Dream'). Should last through until Mid-2015, easily.
well thats interesting. she's already released 4 (kinda) singles. lol does she want each song to be a single? i must say all of them are single worthy but idk bout that
