For music library purposes, hard drive RPM and seek time are unimportant. Seek time is important only if you are reading a lot of small files scattering all over the disk. Music files are relatively large files so don't worry about RPM and seek time.
In fact, I would buy low RPM drives because they are usually quieter. I like the WD green drives. They are variable RPM drives, very quiet, and runs relatively cool. I have six 1T green drives, two of them are almost 2 years old, the other four are 1 year old, never have any problem.
