There's a musical feel to the latest releases on the European App Store, with Gameloft's Guitar Rock Tour and Sonoma's multi-track recorder among Apple's picks of the week.

Gameloft's take on the Guitar Hero/Rock Band genre allows users to play along to 17 tracks while on the move, with the app priced at £4.99/€5.99.

Meanwhile, Sonoma Wire Works'  Fourtrack (£5.99/€7.99) enables users to record audio while on the move, then sync back to proper recording software when back at home.

Also this week French daily newspaper Le Monde debuts its free iPhone app, specialist Mac game developer Aspyr Media has released puzzler Buggled (£1.19/€1.59) and IUGO's platformer Toy Bit Diaries 2 (£2.39/€2.99).
