Hey guys having heard bout the BPM feature recently from a friend i downloaded the new version of scratch however one thing i notice is that i can't seem to get my libary to show it to me after i have set it up. I'm wondering if it could actualy be my audio files that are the problem & what are some good methods of downloading some good quality music?

On the top right corner of the library (under the search box) there is and arrow. Click on the the arrow and a drop down menu will appear.
Make sure BPM is checked, if it's not checked then click on BPM in the drop down menu.
Now you will be able to view your BPMs in your library.

Also make sure when you build overviews that you have "set auto bpm" checked

um quick question off this topic ... if my play back buttons don't work like the cue point 1 2 3 and so on what should be done?

Playback keys only work in INT mode.
Cues are only available in REL and INT mode.
Make sure you don't have "playback keys use shift" checked in the Setup menu

yea i got that one taken care of now it seems fine...but what should i do bout the actual mp3 quality should i be looking at spisific things when downloading?

I try to not use MP3s with a bitrate lower than 192
