Well, If u wanna use windows apps, then wine is the thing. To get wine, u can download the source or the RPM. (RPM recommended if u're a newbie). After installing wine, here's how u use it:
Lets assume u want to run "abc.exe" thats in "d:\baka\abc.exe" in windows.
Firstly, the windows parition should be mounted. (Ask if u dont know how). lets say u have mounted it in /mnt/windoze in linux. So, open a terminal, and "cd /mnt/windoze/baka". Then type "wine abc.exe".
If wine is able to wine this file, then u're lucky, otherwise it'll give some errors, then u're unlucky
If u wanna play MP3s on your system, try software such as XMMS. XMMS is very similar to Winamp in windows. U could also try Xine or something.
Have fun sibu_rajappan
