8tracks
8tracks is another playlist sharing app that allows users to upload MP3s to create customized playlists. The hook — only eight tracks per playlist, hence the name. The Web-based service has received largely high marks for usability and functionality, and this week introduced an iPhone app extension. Users can mark favorite playlists, highlight individual tracks, and create a sort of personalized Internet radio-like stream of all tracks submitted by friends. It also lets users browse submitted tracks by genre or mode, search for specific artists, and buy any track in the system via iTunes.
Wah Wah Pedal
Electrohoof introduced a iPhone/iPad app called Wah Wah Pedal, which lets users manipulate sound by moving the device up and down similar to a traditional guitar pedal. The app comes with a set of preset sounds, but users can also play music stored on the device through the app to manipulate the sound as well, and lets users record their own sound loops as well. Additionally, the “Live Input” mode lets uses play real instruments via the device’s microphone and add various effects.

This is an app that lets users store music in an online “cloud” locker, stream music to any device, and share stored songs with other users. A lawsuit waiting to happen? Probably. Here’s how it works: users can store up to 10 GB of music for free and stream it to any Android phone with the app installed. Users can search for a song or artist via the Android app, and the service will display a list of any matches that other users have uploaded to the locker, allowing users to stream them immediately.
