Console.fm (free): Most knowledgeable music fans got that way in part by poring over the web, attending shows, and talking to other people. The thing is, not everyone has the time to be an expert, which is bad news in particular for members of the electronic music circle, where there's a decided emphasis on one's knowledge and experience. I've heard this referred to as "headiness." For those looking to gain "heady" points without putting in the time, try Console.fm, which tracks the top trending electronic music in a number of genres in a group listening room on the web, and now comes in iOS app form too
GuitarTone (free): While keyboardists have long enjoyed a wealth of sounds and textures at their fingertips (no pun intended), guitarists have been faced with the prospect of spending hundreds, even thousands on an arsenal of less than portable individual effects units, or settling with the limited range of tones from even the best pickup-tube amp combination. No more. Apps that do real-time effects processing for instruments like guitars, basses, and keyboards are improving, thanks to more capable sound engines and minimization of dreaded latency. For example, Amplitube by IK Multimedia opened the doors to a dreamworld of iconic amps and effects that would take a fortune to amass in the real world, but can now be had for the price of a case of beer. Or, if you'd rather just buy that case of beer and enjoy three great amps, four mics, and three different effects without dropping a dime, you might give its free competitor GuitarTone a whirl.
Alchemy Synth Mobile (free): What would any edition of This Week in Music Apps be without at least one free synth? This one in particular furnishes users with 25 free sounds (more available in the Pro version), 25 drum loops via the built in loop player, and remix options for building your own sounds. One-touch chords are also a nice touch, and the copy-paste feature makes using this app with other sequencer apps a snap.
Jell-O Jiggle-It (free; pictured right): Some apps earn mention here just for being bizarre for the way they... wait for it... "break the mold." This app will make the famed Jell-O Jiggler well... jiggle in time to your favorite music, whether from your iPod library or your phone's built-in microphone. We found it amusing, but with substantial rendering requirements, it's best-suited for the iPad or iPhone 4 or better.
Dubstep Wobble Bass ($1): With the dubstep genre gaining popularity (perhaps to the chagrin of its original proponents), so too are apps that help you make your own dubstep. It's just that easy. If you don't believe me, try the Wub Machine, which turns any track under the sun into a wobble-ready dubstep remix. Along the same lines, Dubstep Wobble Bass gives you access to one of the genre's signature sonorities, the wobble bass. Really, what more do you need? Don't answer that.
Rhymezone rhyming dictionary ($2): If you've ever sat down to write lyrics, you know how difficult it can be to find the perfect word that A) says what you mean and B) fits the verse. For these types of problems, old-school printed rhyming dictionaries have been eclipsed by steroid-injected internet databases like Rhymezone.com. Now available in Android app form, this app brings 50,000-plus flow-ready words for you to drop into your own lyrical creations.
MakeItMP3 (free): This app seems to fall in a legal grey area, but it does have non-infringing uses. MakeItMP3 lets users search for videos on YouTube and convert them to MP3s that can be saved and played back locally, which essentially turns the biggest free music streaming service in the world into a download service. We've seen plenty of web apps that do this, but this is the first user-friendly mobile app we've seen that serve this purpose. There is no telling how long it will be around in the official Android store, especially because Google owns both Android.com and YouTube.com, but it's worth checking out -- especially for rare, live performances that may not be available in any other form.
+Music (free): The winner of a social music app contest recently hosted by The Echo Nest (publisher of Evolver.fm), +Music is a Google Chrome app created by developer Peter Watts that adds tons of cool music discovery functionality to the way you interact with Facebook and the web in general. Among other things, it finds tracks as you browse web pages and lets you play them back directly from your browser window as you surf. Not only that, but it can bust out fully-fledged artist stations within your browser, and it puts play buttons on Facebook band pages. (See all Social Media Application Award finalists.)
