Getting those summer blues? Expedia's new music app, the Festival Playlister, will help bring back memories from your favourite music events.

Whether you still get nostalgic about T in the Park last year or want to get your pre-Leeds buzz on while you're walking to work, the new app allows you to search through various events and even create your own playlists. 

Better yet, you can click on whether you want to hear 'mainstream' or 'obscure' score from the event, depending on your tastes.
